PARTICLE-HOLE STRUCTURE OF NUCLEAR ISOMERS AT HIGH ANGULAR MOMENTA

Yrast states are calculated for a number of nuclei with 62 ≦ Z ≦ 72 and 80 ≦ N ≦ 90 on the basis of the deformed Woods-Saxon potential. Particular emphasis is put on the search for the yrast traps. Some new traps, mainly around the neutron number N = 86 nuclei are predicted in the light rare earth region. In particular, five high spin isomers are predicted in the nucleus 152Dy and their magnetic moments are calculated. Calculations are limited to the axially symmetric nuclear deformations. © 1979.
