Microscopic Description of Energy-Levels for Even-Even 124-134Xe Isotopes

The first measured excited states E2(1)(+) and the ratio of the second to the first measured excited states R4/2 = E4(1)(+) / E2(1)(+) the back-bending, the E-GOS and the ratio among the energies of the (I+2) and (I) states as a function of the spin (I) have been drawn to determine the properties of the ground-states band. The odd-even staggering has been drawn to determine the difference between the energies of ground states band (GSB) and negative parity band (NPB). Bohr-Mottelson Model (BM), Interacting Boson Model (IBM-1), Interacting Vector Boson Model (IVBM) and Doma-El-Gendy (D-G) relation have been used to calculate the energy levels of (GSB), IBM-1 has been used to calculate the energy of the gamma band (GB), while IVBM and BM have been used to calculate the energy levels of (NPB). The calculated energy levels in comparison with the measured data indicated the quality of the fitness presented in this work.
