Equilibrium shapes and high-spin properties of the neutron-rich A~100 nuclei

Abstract

Shapes and high-spin properties of nuclei from the neutron-rich (N>56) zirconium region are calculated using the Nilsson-Strutinsky method with the cranked Woods-Saxon average potential and monopole pairing residual interaction. The shape coexistence effects and the competition between rotationally-aligned 1h11/2 neutron and 1g9/2 proton bands is discussed. Predictions are made for the low-lying superdeformed bands in this mass region, characterized by the intruder states originating from the N=5 and 6 oscillator shells.
