Abstract

This research examines the Quantum Phase Transition (QPT) between spherical even-even nuclei (U(5) ) up to the critical point E(5), which has been studied using entanglement entropy in the framework of the Interacting Boson Model 2 (IBM-2). To evaluate this observable, the Tellurium isotopic chain (Te ) has been chosen. The results indicated that the entanglement entropy in the region of U(5)-SO(6) has an increasing trend. Therefore, it is predicted that the isotopes Te(116) and Te(124) are suitable candidates for the symmetry limit U(5) and the critical point E(5), respectively . And the results we obtained from this research are in very good agreement with experimental data and other studies.
