IBM-1 AND SM CALCULATIONS ON THE EVEN-EVEN Fe ISOTOPES

In this work, interacting boson model (IBM) [1] and shell model (SM) [2] calculations have been performed to investigate some nuclear properties of the even-even 50-52Fe and 56-70Fe nuclei along to Z=26 isotopic chain. For this investigation, the energy levels and B(E2) values of these isotopes have been calculated in the scope of interacting boson model-1 and the nuclear shell model. The multipole Hamiltonian form was selected for the IBM-1 calculations. For the shell model calculations, 20Ca nucleus was considered as inert core and pfg single particle orbitals on this core were used as the model space. Different nucleon-nucleon interactions were used for two-body effective interactions. KShell, NuShell and Bigstick softwares were used for the SM calculations. The obtained results have been compared with each other and the experimental data [3,4]. A good agreement was observed between them.
