Xenon isotopes 124-134 Xe (Z=54) varying from gamma-soft rotor O(6) to along near-harmonic vibrator SU(5). Energy levels, Electromagnetic transitions B(E2), B(M1), mixing ratio ( ) 1 / 2 M E δ and monopole transitions ( ) 0 E B for selected transitions in 124-134 Xe are calculated in the frame work of collective model proton-neutron Interacting boson model (IBM-2). The results obtained for 124-134 Xe are reasonably in a good agreement with the previous experimental results.

The interacting boson model (IBM-1) is used to calculate the energy levels, transition probabilities í µí°µ(í µí°¸2), and potential energy surfaces of some even 120−126 Xe isotopes. The theoretical values are in good agreement with the experimental data. The potential energy surface is one of the nucleus properties, and it gives a final shape of nuclei. The contour plot of the potential energy surfaces shows that the 120−126 Xe nuclei are deformed and have í µí»¾-unstable-like characters.

In this study, the multi-quasiparticle triaxial projected shell model (TPSM) is applied to investigate -vibrational bands in transitional nuclei of . We report that each triaxial intrinsic state has a -band built on it. The TPSM approach is evaluated by the comparison of TPSM results with available experimental data, which shows a satisfactory agreement. The energy ratios, B(E2) transition rates, and signature splitting of the -vibrational band are calculated.

The nuclear structure of 134 Ce isotope has been studied within the framework of the Interacting Boson Model (IBM-1). The dynamical symmetry has been determined depending on the ratios of the Experimental Energy of E4 1 +/E2 1 + which is in agreement with theoretical values. Also, the energy levels, g, γ, β1 bands have been calculated and compared with the experimental data and which is showed agreement between them. In addition to that, the reduced probability of quadrupole electric transitions, B(E2) values for 134 Ce isotope have been calculated and compared with available experimental data. The calculated results are in good agreement with the experimental data. The potential Energy surface (E(N, β, γ)) have been calculated and these properties show that the shape of 134 Ce isotope isotopes is γ-unstable and it has the O(6) limit.

Different Skyrme functional parametrizations were tested for Te, Xe, Ba and Ce isotopes for N > 82. For the SVsym34 parametrization, which best fits the experimental binding energy, potential energy curves obtained from constrained β 2 , β 3 and β 4 Hartree-Fock+BCS calculations were investigated. Positions of the lowest quadrupole and octupole vibrational states and the lowest 2 + rotational states in deformed nuclei were obtained within the Skyrme QRPA and compared to existing experimental data.

The experimental data is used to investigate the level structures of 130-136 Ce isotopes. The values from the Dynamic deformation model (DDM) and the Interacting Boson Model-1 (IBM-1) are compared to the level energies, E2 moments, and B(E2) ratios for transitions from the 2 K and 2 0 bands (IBM-1). On the basis of the expected Kcomponents and the decay mode, the newly assigned 1.672 MeV) 4 , 3 , 2 (J state in 130Ce is tentatively associated with 4 J. This K = 4 band is correlated with the 2.068 MeV) 6 , 5 , 4 (J state. The 1.932 MeV 4 J level in 132 Ce is associated with band.

Properties of 114 134 Xe  isotopes are studied in the (5) (6) U SO  transitional region of Interacting Boson Model (IBM-1). The energy levels and ( 2) BE transition rates are calculated via the affine (1,1) SU Lie Algebra. The agreement with the most recent experimental is acceptable. The evaluated Hamiltonian control parameters suggest a spherical to   soft shape transition and propose the 130 Xe nucleus as the best candidate for the (5) E symmetry.

In this proposal study, the mainly fitting Hamiltonian have been determined, to is wanted used for the near calculations of power levels also B(E2) values of even-even for 52 Te with mass number (114≤ A ≤ 118 nuclei using the interacting boson type (IBM-1). Using the best fixed values of parameters in the Hamiltonian of the IBM-1, the energy levels, B(E2) and the electric quadruple moment value for a numeral of transitions in even-even isotopes series will be calculated. The results will be compare with a recent experimental data also with the theoretical calculated by using (IBM-1) and must it was observe so that they are in excellent concord. It will turn out that the interacting boson estimate (IBA) is fairly reliable for calculating spectra in the entire set of even-even 114-118 Te isotopes. Also the branching ratios R', R'', R''' will be study it and the importance of studying the branching ratios is to locate the position of our isotopes 114-118 Te relative to the dynamical symmetry U(5).Studying the surface potential energy using the equations of the Hamilton function.

In this work, the ground state, quasi beta and quasi gamma band energies of 114,116,118,120 Xe isotopes have been investigated by using the both (IBM-1 and IBM-2) versions of interacting boson model (IBM). In calculations, the theoretical energy levels have been obtained by using PHINT and NP-BOS program codes. The presented results are compared with the experimental data in respective tables and figures. At the end, it was seen that the obtained theoretical results are in good agreement with the experimental data.
