Abstract

A shell-model description of the structure of low-energy states of heavy deformed nuclei is used to predict the number and strengths of 1+ states that couple to the ground state via a strong M1 transition. Results are given for the magnetic moments of 2g+ states of various Gd, Er, U, and Pu isotopes and also the M1 transition strengths 1+ → 0g+, 1+ → 2g+, and 1+ → 2γ+ for several rare earth and actinide nuclei. © 1987.
