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 1h112 neutron and 1g92 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.

      Thus, as we go down on the proton scale at Z = 38 (i.e., Z < 38), the nuclei are found to possess deformed nature due to proton and neutron excitations, thereby, developing some amount of quadrupole deformation in these nuclei. Several experimental [3–7] and theoretical [8–11] studies have been devoted in the past to better characterize the structural evolution of the ground and excited states in this region. The development of techniques utilizing heavy-ion-induced reactions in high-spin spectroscopy has led to the observation of new rotational features in odd-odd deformed nuclei, including odd-even staggering, signature inversion, and delay in band-crossing frequencies [12].
