Abstract
The phenomenon of the coexistence of nuclear shapes in 70,72,74Se is studied within the framework of the deformed configuration mixing shell model. In this model, 56Ni is taken as the core with the valence space consisting of 1p3/2, 1p1/2, 0f5/2 and 0g9/2 orbitals. An effective interaction given to Kuo and modified by Ahalpara and others has been used. The crossing of a nearly spherical ground state band and a highly deformed band in 70,72Se are given by the calculation in agreement with experiment. The calculation does not show any such band crossing in 74Se. The role of the g9/2 orbital in producing highly deformed two neutron aligned bands is stressed.Keywords
