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 a monopole pairing residual interaction. The shape coexistence effects and the competition between rotationally aligned 1h 11 2 neutron and 1g 9 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.
