This book was released on 1981 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is the purpose of the present paper to develop a molecular beam technique for recording continuously the concentration of chemical species behind the incident shock wave in a shock tube. The sample is drawn through a diverging nozzle located at the end of the low pressure section of the shock tube. The inlet diamters of the nozzles are 1-4 mm. It is assumed that the expansion is so fast that freezing of chemical reactions occurs. With a skimmer a molecular beam is formed which is analyzed with a quadruopole mass filter. Preliminary experiments were performed with N2 and binary mixtures of N2 and O2 at initial pressures between 1 mbar and 10 mbar and at Mach numbers ranging from M(s) = 6 to M(s) = 12. Experimental results are compared with intensities which are determined theoretically assuming a Maxwellian distribution function behind the incident shock.

Available in PDF, EPUB and Kindle. Book excerpt: This Open Access book gives a comprehensive account of both the history and current achievements of molecular beam research. In 1919, Otto Stern launched the revolutionary molecular beam technique. This technique made it possible to send atoms and molecules with well-defined momentum through vacuum and to measure with high accuracy the deflections they underwent when acted upon by transversal forces. These measurements revealed unforeseen quantum properties of nuclei, atoms, and molecules that became the basis for our current understanding of quantum matter. This volume shows that many key areas of modern physics and chemistry owe their beginnings to the seminal molecular beam work of Otto Stern and his school. Written by internationally recognized experts, the contributions in this volume will help experienced researchers and incoming graduate students alike to keep abreast of current developments in molecular beam research as well as to appreciate the history and evolution of this powerful method and the knowledge it reveals.

Available in PDF, EPUB and Kindle. Book excerpt: Recent Research in Molecular Beam is a collection of scientific papers that have been inspired by Otto Stern, the founder of Molecular Beam Research. This book is composed of 10 chapters and begins with discussions on the early history of molecular beam research. The next chapters describe the velocity distribution measurements made on potassium molecular beams with a fixed-frequency, variable phase velocity selector, along with a brief consideration of the principles and concepts of electron magnetic moment and atomic magnetism. A chapter presents the atomic beam spectroscopic experiments on the metastable state of the hydrogen-like atoms that depend on a wholly different principle for the detection of transitions. This text further explores the effects of variations in the oscillatory field amplitudes, perturbations by neighboring resonances, perturbations by oscillatory fields, variations in the fixed field amplitudes, and phase shifts of the oscillatory fields. These topics are followed by a comparison of advantages and limitations of various techniques for spin property measurement as they apply in particular to radioactive nuclei, such as optical and molecular gas microwave spectroscopy, nuclear and paramagnetic resonance, and atomic beams. The remaining chapters examine fluid friction in a rarefied gas flow; some applications of molecular beam techniques to chemistry; and the polarized neutrons based on a Stern-Gerlach experiment. This work will be of great value to workers and researchers in molecular beam field.

Download or read book Molecular Beams written by Norman Ramsey and published by Oxford University Press. This book was released on 1956 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1956, this classic work by N.F. Ramsey, 1989 Nobel Laureate in Physics, provides an account of atomic and molecular structure. After an introductory section reviewing experimental apparatus and the kinds of quantities that can be measured, Ramsey provides comprehensive accounts of gas kinetics, chemical equilibria, and atomic and nuclear magnetic moments by nonresonance methods. He also provides tables of nuclear moments, as well as detailed accounts of nuclear and molecular interactions. Finally there are sections on atomic fine and hyperfine structure, and the design of experimental apparatus. The focus throughout is on the physics of beams composed of electrically neutral particles. As a seminal work by one of the world's leading scientists, this volume will interest students and researchers in a range of fields, including atomic physics, physical chemistry, spectroscopy, and biological chemistry.
