A systematic study in the region of N=86-98

Abstract

In this work a systematic study was performed in the region of N=86-98 by means of Total Routhian Surface (TRS) calculations. TRS calculations are based on Woods-Saxon potential in the framework of cranked shell model (CSM) and Bogolyubov-Strutinsky approach. The deformed mean field is capable of making predictions on nuclear deformations and other observables Eke moments of inertia and quadrupole moments. These observables are calculated for the region of interest and compared with the experimental data. The regime, in which the TRS approach can be used successfully, covers of neutron number N >= 88. In particular these nuclei which are assigned to be situated at a point of phase transition, having X(5) symmetry can be described by mean field calculation.
