Investigation of even-even nuclei at around A-160 with the coherent state approximation

Shape phase transitions, which indicate the structural changes observed due to the change of the nucleon number in the atomic nucleus, are important topics of nuclear physics. Interacting Boson Model (EBM) and Collective Model. These two models, which are completely opposite to each other, are connected by the Coherent State Approach (CSA). In this study, the structures of even-even nuclei with a mass number of 160 were investigated using EDY. For this purpose, twenty double-double isotopes were chosen. Energies of the ground state, beta and gamma bands were calculated for each selected isotope. Electric quadrupole transition rates were also calculated for the ground state band. The obtained theoretical findings were compared with the experimental data and it was seen that there was a very good agreement between them.
