Description of yrast states and deformation changes in tantalum nuclei (Ta)

Abstract

The gamma - ray studies of 167Ta nucleus will be studied and several rotational decay sequences are identified. In these nuclei values for the effective moment of the inertia are suggested which reproduces the energies of the non-yarst states, that are populated in decay of the isomer. The results are discussed in comparison of the energy level patterns for the tantalum isotopes with exiting data in the neighboring nuclei and thus has been done by studding the changes in deformation through the so called "Gaige Plots"
