“…The low-lying states showing a rich collective structure in this region were investigated extensively in terms of the pair-truncated shell model (PTSM) [5] and the relativistic Hartree-Fock Model (RHFM) [6]. The Xe [7][8][9][10][11][12][13][14][15][16], Ba [3,[16][17][18] and Te [19][20][21][22][23] region with the mass number A ~ 120-130 has recently been studied experimentally and interpreted by several models [24][25][26][27][28][29][30].

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.

“…In fact, the A ∼ = 120-130 mass region is lying above the Z = 50 proton gap but below the N = 82 neutron gap and it is the only region of heavy nuclei in which this conflicting situation can be experimentally investigated in a systematic way [1]. Recently, The Xe [2][3][4][5][6][7][8][9][10], Ba [10][11][12][13] and Te [14][15][16][17][18] region with the mass number A ∼ = 120-130 has been studied experimentally and interpreted by several models [19][20][21][22][23][24][25]. Prochniak et al [26] applied the general Bohr Hamiltonian (GBH) to a description of low-lying collective excitations in even-even isotopes of Te, Xe, Ba, Ce, Nd and Sm and investigated the low-lying collective states in even-even nuclei along the region of 50 < Z, N < 82.…”

The interacting boson model (IBM) has been widely used for describing the quadrupole collective states of the medium-heavy nuclei and no distinction is made between proton and neutron variables when the first version of the model is applied. However, the neutrons' and protons' degrees of freedom are described explicitly in the second version of the model (IBM-2). Moreover, the microscopic foundations certainly state that it is very important to describe the proton and neutron variables explicitly and this is also the generalized definition of the second version of the IBA model (IBM-2 model). So, triaxiality can be described explicitly through the introduction of cubic terms in the boson operators. Using the best-fitted values of parameters in the Hamiltonian of the IBM-2, we have calculated energy levels and B(E2) values for a number of transitions in 122,124,126,128,130,132,134Xe. The results were compared with the previous experimental and theoretical data and it has been observed that they are in good agreement. Many B(E2) values that are still not known so far are stated and the set of parameters used in these calculations is the best approximation that has been carried out so far. It has also turned out that the IBA and Bohr–Mottelson Hamiltonian with Davidson potential are fairly reliable models for the calculation of spectra in the entire set of 122,124,126,128,130,132,134Xe isotopes.

“…The matrix elements of the E2 operator of eq. Even-even Ba [22][23][24][25] and Te [26][27][28][29][30][31] are also the member of the chain existing along the mass region of A ∼ 120-130 and they are neighboring isotopes to Ce nuclei. Yoshinaga and Higashiyama [32] have stated that the experimental data of 130−134 Ba simulate the O(6) limit prediction of IBM.…”

In this study, we determined the most appropriate Hamiltonian that is needed for the present calculations of energy levels and B(E2) values of 128−138 Ce nuclei which have a mass around A ∼ = 130 using the interacting boson model (IBM). Using the bestfitted values of parameters in the Hamiltonian of the IBM-2, we have calculated energy levels and B(E2) values for a number of transitions in 128,130,132,134,136,138 Ce. The results were compared with the previous experimental and theoretical (PTSM model) data and it was observed that they are in good agreement. Also some predictions of this model have better accuracy than those of PTSM model. It has turned out that the interacting boson approximation (IBA) is fairly reliable for calculating spectra in the entire set of 128,130,132,134,136,138 Ce isotopes and the quality of the fits presented in this paper is acceptable.
