“…In this case it is invariant under the inversion of the sign of the d-boson operators. This d-parity operation [38,71,73] P d : d ρ → −d ρ , s ρ → s ρ (ρ = π, ν) does not change the Hamiltonian for χ π = χ ν = 0 since it contains only terms with an even number of dboson operators. Due to this d-parity symmetry of the special Hamiltonian with χ π = χ ν = 0 its eigenstates have a good d-parity π d .…”

“…The Hamiltonian sets of parameters which have been varied along the isotopic chain are shown as a function of the neutron number for Ce isotopes in figure 1a. As seen, the large variation between Ce and the neighboring Te-Xe-Ba [16][17][18] isotopes points in the same direction.…”

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.

“…Calculations of positive and negative-parity states and the electromagnetic transitions of odd mass nuclei have performed within the framework of IBFM, for instance in Refs. [19,20,21,22,23,24]. One of most important property in nuclear structure study is the β decay rates.…”

We have investigated the negative-parity states and electromagnetic transitions in 151,153 Ho and 151,153 Dy within the framework of the interacting boson fermion model 2 (IBFM-2). Spin assignments for some states with uncertain spin are made based on this calculation. Calculated excitation energies, electromagnetic transitions and branching ratios are compared with available experimental data and a good agreement is obtained. The model wave functions have been used to study β-decays from Ho to Dy isotones, and the calculated log f t values are close to the experimental data.
