Book Description
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.

Book Description
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.
