In this study, we determined the most appropriate Hamiltonian that is needed for present calculations of nuclei in the A≅130 region by the view of projection of IBM-2 parameters onto IBM-1. The interacting boson model 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 (IBM-1) is applied. So, triaxiality can be described explicitly, through the introduction of cubic terms in the boson operators. However, the microscopic foundations state certainly that it is very important to describe the proton and neutron variables explicitly. This is also a generalized definition of the second version of the IBA-model (IBM-2 model). 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 144,146,148,150,152,154Nd. The results were compared with the previous experimental and theoretical data and it is 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 turned out that the interacting boson approximation (IBA) is fairly reliable for the calculation of spectra in the entire set of 144,146,148,150,152,154Nd isotopes.

“…Saladin et al, [3] investigated evidence for continuum E0 transitions following the decay of high-spin states in 130 Ce isotope, while Wells et al, [4] uncovered evidence for collective behavior in 128 Ce isotope through lifetime measurements. There has been no extensive work on the structure of cerium nuclei hence calculations that are equivalent to experimental data are required.…”

Using the Interacting Boson Model-2 (IBM-2), we determined the most appropriate Hamiltonian for the current calculations of energy levels and electromagnetic transition probability values of 124-138Ce nuclei with a mass around A=140 in this study. We estimated energy levels and electromagnetic values and mixing ratios (E2/M1) for a number of transitions in 124-138Ce isotopes using the best fitted values of parameters in the IBM-2 Hamiltonian. When the results were compared to the experimental data, they were found to be in good agreement.

“…In earlier studies on 130,132,134 Ce, Husar et al [1] and Nolan et al [2] obtained both energy level spacing and life-time results which indicated increased collective behavior with decreasing neutron number. Wells et al [3] obtained evidence for collective behavior in 128 Ce from lifetime measurements, Saladin et al [4] studied evidence for continuum E0 transitions following the decay of high-spin states in 130 Ce. No detailed work has been done on the structure of cerium nuclei and it is necessary to carry out calculations that are comparable to experimental results.…”

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.
