Construction of an Anticompton- gamma -Spectrometer and Study of Yrast States of Nuclei in the Ca-Region

摘要

In the present thesis the yrast states of nuclei in the Ca-region are studied using gamma -spectroscopy. For this case an anticompton- gamma -spectrometer for the reduction of the Compton-background was constructed and taken into operation. The results obtained for the nuclei exp 42 Ca and exp 40 K are presented in the present thesis. The studies of the decay chains are based on gamma gamma -coincidence measurements, on measurements of the angular distribution for the determination of the spin changes, and on measurements of the excitation function for the study of the spin population in the final nuclei using the reactions exp 27 Al( exp 19 F,xyz gamma ) exp 42 Ca, exp 40 K.
