Measurement of Quantum and Particle Energies With Scintillation Counters
Abstract
In this thesis I have given an account of work carried out with scintillation counters on the measurement of quantum and particle energies.The main application has been to the measurement of £-ray and Y-ray energies as a means of determining the decay schemes of radioactive isotopes.In Part I a general introduction to the subject of energy measurement is given which includes a critical survey of other techniques and an indication of the scope for new ones.This part is taken from a variety of sources, including Moonfs "Artificial Radioactivity" (Moon 1949) and a number of original papers which are referred to in the text.Part II is a more detailed introduction dealing with the scintillation counter itself, and it is drawn from the now fairly extensive literature on the subject.Part III contains a description of the scintillation counter as developed by the writer for use in 0-and Y-ray energy measurements.Part IV deals with an original application of the Compton effect to Y-ray spectroscopy, which was suggested by Dr. S.C. Curran and developed and used by the writer.In Part V, the techniques used in studying decay schemes and the results obtained for three different sources are described.One of the techniques used here, the integrated spectrum method, is a new applic ation of a 4tt counting geometry to such problems.In the work on La140 the writer was assisted in the interpretive aspects of the problem by Mr. G.M. Lewis and Dr. S.C. Curran, while in the case of BaD the…
