Studying of deformation effect on energy levels in heavy nuclei region

Abstract

The work aims to study nuclear structure for some heavy nuclei Using the first interactingbosons model (IBM-1) and it calculated low-lying structure levels To determine the type ofdynamic symmetry that those isotones belongs to it (178Yb, 180Hf, 182W, 184Os ) It has beenpredicted angular momentum and parity for some energy levels that have not been adefinite to be a specific has been confirmed each other and find the momentum andsymmetry of some of the other not previously denitrified practically
