Abstract
The density dependent point coupling and meson exchange effective interactions are employed in the relativistic Hartree-Bogoliubov (RHB) model to study the development of ground state deformation and occurrence of shape transitions with change of neutron number in 104−144Te isotopes. Besides this, the systematics of other nuclear structure properties with increasing neutron number are also obtained. The RHB model reproduces well the available experimental data on binding energies, quadrupole deformation parameters, two neutron separation energies and root mean square charge radii. The results of three-dimensional potential energy surfaces predict prolate ground state minima for proton rich and neutron rich tellurium isotopes, oblate minima for 114−124Te, triaxial minima for 126,128Te and spherical minima for 130−134Te. Besides, oblate prolate shape coexistence is predicted in 116−120Te isotopes.
