Abstract

In the present paper, the systematic investigation of potential energy surfaces (PESs) has been presented in order to study the development of shape evolution with the variation in neutron number in the ground states of axially deformed even-even 104−144Te isotopes. Relativistic-Hartree-Bogoliubov model has been employed to study PES plots with the help of density-dependent point coupling effective parameters (DD-PCX). The obtained results have predicted the shape transition from prolate to oblate, oblate to spherical and spherical to prolate deformation in these isotopes. The calculated results have also predicted the shape coexistence in 116, 118, 126, 128Te isotopes. Besides this, various ground state properties like mass excess, two neutron separation energies, root mean square radii of neutrons and protons and charge radii have also been studied as a function of neutron number. The calculated results are also compared with the published theoretical results by using DD-ME2, DD-PC1, PC-PK1, BSkG2, FRDM and Gogny D1S interactions and are found to be in good agreement with predictions made by the relativistic mean field calculations employing the DD-ME2, DD-PC1, PC-PK1 interaction parameters.
