Abstract

Nuclear shape change and shape coexistence in the Selenium isotopes have been investigated by TotalRouthianSurface(TRS) calculations. It is found that nuclear shapes vary significantly with increasing neutron number. The TRS calculations for the ground states of 66, 72, 92, 94Se isotopes show that both neutrondeficient and neutrondripline Selenium isotopes have oblate and prolate shape coexistence. The cranking shellmodel calculations for 72, 94Se give that prolate and oblate shape coexistence in low rotational frequency. However, oblate rotational bands disappear and prolate rotational bands become yrast bands with increasing rotational frequency, which is due to the intrusion of the g9/2 orbitals.
