Reduced Probabilities for E1 and E2 Transitions in Alternating-Parity Spectra of Heavy Even-Even Nuclei

摘要

Reduced probabilities for intra/interband E1 and E2 transitions to alternating-parity states of the yrast and first nonyrast bands in Nd-150, Sm-154, Gd-154,Gd- 160, and Er-162,Er- 164 lantanide and Th-232 and (236,238)u actinide nuclei are studied. The values calculated for B(E1) and B(E2) are compared with available experimental data. Variations in the surface deformation of nuclei upon a collective excitation are taken into account.
