Available in PDF, EPUB and Kindle. Book excerpt: The use of a beta-ray spectrometer, in the analysis of nuclear decay schemes, makes possible the solution of many of the problems which arise in the course of such analyses. Of particular interest is the application of the instrument to the determination of the energy of beta and gamma-radiation from radioactive isotopes. In addition, it is possible to use the instrument to estimate the relative intensities of the various components of radiation; and to apply the coincidence method, in conjunction with the spectrometer, to the determination of the order in which these components are emitted from the nucleus. The present work was concerned with three particular problems arising in beta-ray spectrometry. A method of improving the intensity-resolution relationship of a thin lens magnetic beta-ray spectrometer, by means of ring focusing, was investigated. The existence of a ring-shaped constriction in the electron beam was demonstrated experimentally by a photographic film method. A theoretical analysis was carried out in an attempt to determine relations from which the relative intensities of beta-rays, gamma-rays and internal conversion electrons might be determined from data obtained with the spectrometer. Simplifying assumptions were made concerning the focusing action of the instrument, and effects due to scattering of electrons in the source of photoelectric radiator were neglected. Formulae were derived from which the observed spectrometer counting rates due to sources of known activity, emitting beta-rays, gamma-rays or internal conversion electrons may be predicted.

Available in PDF, EPUB and Kindle. Book excerpt: Alpha-, Beta- and Gamma-Ray Spectroscopy Volume 1 offers a comprehensive account of radioactivity and related low-energy phenomena. It summarizes progress in the field of alpha-, beta- and gamma-ray spectroscopy, including the discovery of the non-conservation of parity, as well as new experimental methods that elucidate the processes of weak interactions in general and beta-decay in particular. Comprised of 14 chapters, the book presents experimental methods and theoretical discussions and calculations to maintain the link between experiment and theory. It begins with a discussion of the interaction of electrons and alpha particles with matter. The book explains the elastic scattering of electrons by atomic nuclei and the interaction between gamma-radiation and matter. It then introduces topic on beta-ray spectrometer theory and design and crystal diffraction spectroscopy of nuclear gamma rays. Moreover, the book discusses the applications of the scintillation counter; proportional counting in gases; and the general processes and procedures used in determining disintegration schemes through a study of the beta- and gamma-rays emitted. In addition, it covers the nuclear shell model; collective nuclear motion and the unified model; and alpha-decay conservation laws. The emissions of gamma-radiation during charged particle bombardment and from fission fragments, as well as the neutron-capture radiation spectroscopy, are also explained. Experimentalists will find this book extremely useful.

Available in PDF, EPUB and Kindle. Book excerpt: The beta spectrum of the main inner group of 89.0-hr Re-186 has been magnetically analyzed in coincidence with the 137.2-kev gamma. The observed spectrum does not have the allowed shape nor the unique shape; its spectrum shape correction factor increases ca 18% from 150 kev to 900 kev. Subtraction of this spectrum, weighted with its measured relative abundance, from the composite spectrum, produces the spectrum of the ground state transition. Its similarly allowed, non-unique shape factor increases by ca 22% from 150 kev to 1050 kev. Both transitions are interpreted as first forbidden; RE-186 is assigned a ground state spin and parity. A theoretical parametric fitting of these spectra with the combination of scalar and tensor beta interactions is demonstrated the limited ranges of the fitting parameters, which are functions of the nuclear matrix elements, are obtained.
