Available in PDF, EPUB and Kindle. Book excerpt: Mössbauer Effect: Principles and Applications focuses on the processes, methodologies, and reactions involved in Mössbauer effect, as well as atomic motion, use of the effect in studying hyperfine structures, quadropole coupling, and isomer shift. The manuscript first discusses resonant absorption, emission of gamma rays by nuclei, width of gamma-ray spectrum, and emission from bound atoms. The text then surveys counting, modulation, and low-temperature techniques. The publication offers information on relativity and the Mössbauer effect, atomic motion, quadropole coupling, and magnetic hyperfine structure. Discussions focus on gravitational red shift and combined magnetic and electric hyperfine coupling. The text then evaluates magnetism of metals and alloys, chemical applications, and linewidth and line shape. The manuscript is a valuable source of data for physicists and readers interested in the Mössbauer effect.

Book excerpt: This paper considers from a simple physical point of view the Mossbauer effect, i. e., the 'recoilless emission' of gamma-rays from a nucleur bound in a crystal lattice. It begins with a discussion of the kinematics of gamma-ray emission from such a nucleus. The idealized case of a massive 'lattice' characterized by a single frequency and the more realistic one and three-dimensional models are treated. We point up the fact that in the Mossbauer effect the lattice as a whole (the lattice center of mass) always recoils after photon emission, so that the term 'recoilless emission' is in one sense misleading. We emphasize that the essence of the Mossbauer effect is not photon emission without recoil, but rather is photon emission without transfer of energy to internal degrees of freedom of the lattice. Using the basic ideas of quantum mechanics, namely, the rules for the manipulation of probability amplitudes (the socalled 'transformation theory'), we calculate the probability for recoil without excitation of internal degrees of freedom, i. e., the Mossbauer f-factor, on the assumption that the individual photon emissions, consequent lattice recoil, are instantaneous. In Appendix A we discuss this question of instantaneous emission in some detail, and show how it is not in contradiction with the fact that the nuclear transition that leads to the gamma-ray emission has a finite half-width. In Appendix B those rules of transformation theory that are used in the body of the paper are summarized. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The effect which now bears his name, was discovered in 1958 by Rudolf Mössbauer at the Technical University of Munich. At first, this appeared to be a phenomenon related to nuclear energy levels that provided some information about excited state lifetimes and quantum properties. However, it soon became apparent that Mössbauer spectroscopy had applications in such diverse fields as general relativity, solid state physics, chemistry, materials science, biology, medical physics, archeology and art. It is the extreme sensitivity of the effect to the atomic environment around the probe atom as well as the ability to apply the technique to some interesting and important elements, most notably iron, that is responsible for the Mössbauer effect's extensive use. The present volume reviews the historical development of the Mössbauer effect, the experimental details, the basic physics of hyperfine interactions and some of the numerous applications of Mössbauer effect spectroscopy.

Available in PDF, EPUB and Kindle. Book excerpt: This is the fifth volume of a series which provides acontinuing forum for publication of developments in Mossbauer effect methodology and of spectroscopy and its applications. Mossbauer Effect Methodology, Volume 5, records the proceedings of the Fifth Symposium on Mossbauer Effect Methodology. The sym posium was sponsored by the New England Nuclear Corporation and was centered on the themes of spectroscopy, new applications, and methodology. The symposium was held in the Mercury Ballroom of the New York Hilton hotel on February 2, 1969. Dr. P. A. Flinn of Carnegie Mellon Institute was chairman of the afternoon and evening sessions. About three hundred participants attended, and this degree of interest leads us to anticipate a sixth symposium early in 1970. Elron Electronic Industries and Reuter-Stokes Electronic Components Company demonstrated lines of equipment for Mossbauer investigators. The evident high quality of the commercial instrumenta tion available is a tribute to the growth of Mossbauer technology and to the manufacturers.

Available in PDF, EPUB and Kindle. Book excerpt: Mossbauer Effect Methodology, Volume 1, records the proceedings of the First Symposium on Mossbauer Effect Methodology. This Symposium was sponsored by the New England Nuclear Corporation and the Technical Measurement Corporation, and was devoted to principles, techniques, and applications of the Mossbauer effect. The Symposium was held at the Sheraton-Atlantic Hotel in New York City on january 26, 1965. Dr. Stanley Ruby, of Argonne National Laboratory, was Chairman of the aU-day session. About 250 people attended the Symposium, and interest appeared sufficient to warrant continuation of this Symposium series. It is hoped that future Symposia can be organized which will serve as a forum for presentation of advances in methodology. The papers presented in this volume review the current status of applications, describe instrument systems used, elu cidate measurement techniques applied, and formulate means of creating required environments for use in Mossbauer effect studies. With the proliferation of applications of the Mos sbauer effect in physics, as well as in chemistry and biology, the need for complete description of transducer systems, detection and data handling methods, and environment modification techniques be came apparent. The body of such experience, developed and possessed by a relatively small group of physicists, primarily, has not been readily accessible to those in other fields. The editor organized this Symposium in response to many expres sions of a need for such information.

Available in PDF, EPUB and Kindle. Book excerpt: The continued growth of Mössbauer effect methodology, and its virtuosity in encompassing new elements and new applications, are amply illustrated by the contents of this volume. The degree of maturity of Mössbauer spectroscopy is attested to by the increasing reliance of chemists upon Mössbauer investigation as a primary tool to be conjirmed by more "conventional" measurements. An exciting development has been the use of neutron and Cou lomb excitation techniques to produce Mössbauer Ievels. This promises to Iead Mössbauer spectroscopy toward the very desirable "universal spectroscopy" category. The prospect of extending the technique to many elements which do not possess useful precursor radionuclides is exciting indeed. While attention is being focused primarily on spectroscopy and applications, methodology is not being neglected. Another generation of drive designs is being reported, and commercial spectrometers are becoming more reliable, more competitive, and offer a reasonable selection of features at a wide range in prices. Several of the equipment companies who participated in the Third Mössbauer Methodology Symposium demonstrated approaches to Mössbauer spectrometer design (e.g., Austin Science Associates and Linear Alpha Corpora tion-Elron). A unique, new, very high countrate acceptance system demonstrated by Austin Science Associates was developed entirely in response to the need of Mössbauer spectroscopists for data acquisition rates beyond existing proportional counting capabilities. The range of proportional detectors available and a simple, inexpen sive demonstration spectrometer were exhibited by Reuter-Stokes Electronic Components, Inc.

Book excerpt: This is the ninth volume of a continuing series intended to provide a forum for publication of develop ments in Mossbauer effect methodology and in spectroscopy and its applications. Mossbauer Effect Methodology, Volume 9, records the proceedings of the Ninth Symposium on Mossbauer Effect Methodology. The symposium was sponsored by the New England Nuclear Corporation and interest was concentrated on spectroscopy and applications, with more than usual emphasis on new methodology. The symposium was held in the Palmer House in Chicago on February 3, 1974. Dr. Stanley Hanna presided over the afternoon and evening sessions. Attendance was lower than usual; about one hundred participants were present. This may reflect the continu ing pressure of travel budget limitations. Contributing Sponsors were Austin Science Associates, El Scint, Inc., Nuclear Science Instruments and Ranger Electronics. These organizations demonstrated their products for Mossbauer applications. The continuing improvements in the spectrometers and their adjuncts was evident. The Selection Committee again had a most difficult task, and was obliged to accept only about half of the submitted papers. A most interesting group of papers on applications and spectroscopy featured reports on electronic relaxation phenomena, magnetic phase and spin transformations, photochromism in strontium titanate, lattice studies, and phase determination by Kossel analysis. The excellent methodology session included presentations on data analysis techniques for spectral folding, hyperfine interaction analysis and recoil-free fraction measurement, a backscatter spectrometer and a report on a Selective Excitation Double Mossbauer method to study time-dependent phenomena.

Available in PDF, EPUB and Kindle. Book excerpt: This up-to-date review closes an important gap in the literature by providing a comprehensive description of the Mössbauer effect in lattice dynamics, along with a collection of applications in metals, alloys, amorphous solids, molecular crystals, thin films, and nanocrystals. It is the first to systematically compare Mössbauer spectroscopy using synchrotron radiation to conventional Mössbauer spectroscopy, discussing in detail its advantages and capabilities, backed by the latest theoretical developments and experimental examples. Intended as a self-contained volume that may be used as a complete reference or textbook, it adopts new pedagogical approaches with several non-traditional and refreshing theoretical expositions, while all quantitative relations are derived with the necessary details so as to be easily followed by the reader. Two entire chapters are devoted to the study of the dynamics of impurity atoms in solids, while a thorough description of the Mannheim model as a theoretical method is presented and its predictions compared to experimental results. Finally, an in-depth analysis of absorption of Mössbauer radiation is presented, based on recent research by one of the authors, resulting in an exact expression of fractional absorption, otherwise unavailable in the literature. The whole is supplemented by elaborate appendices containing constants and parameters.

This book was released on 2012-12-06 with total page 784 pages. Available in PDF, EPUB and Kindle. Book excerpt: As is often the case, the preface is the last task to be finished during the preparation of a large volume such as you are now holding. The first task, obtaining approval for a symposium on the industrial applications, now seems a long time ago. The idea orginated with John Stevens, probably in 1982, from his observation of papers dealing with industrial applications of the Mossbauer effect appearing in the Mossbauer Effect Reference and Data Journal. His initial suggestion for a symposium entitled "Industrial Applications of the Mossbauer Effect" to be held at a national meeting of the American Chemical Society eventually led to the symposium at the International Chemical Congress of Pacific Basin Societies which met in Honolulu, Hawaii in December 1984. This volume is the result of the symposium at the above mentioned Congress, but is not actually the 'proceedings' of the symposium because this volume does not contain all of the over one hundred Mossbauer effect papers that were pre sented at the symposium. Rather it contains a selection of papers that the or ganizing committee for the symposium deemed most appropriate for a volume devoted to industrial applications of the Mossbauer effect. The final volume also contains six chapters that were not a part of the symposium but which are closely related to the topic. There is another difference from many proceedings.
