| Abstract | ||||
| Everything in the universe is made up of atoms, which are mediated by the nucleus. The understanding of the complex structure of the nucleus of atoms is still one of the major challenges. Therefore, the physics of rich neutron nuclei is one of the most subjects in nuclear structure physics both theoretically and experimentally. The Hartree-Fock-Bogolyubov (HFB) theory has a good theoretical framework for describing these nuclei since it is generalized the Hartree-Fock approximation with BCS pairing theory. In this work, the neutron skin thickness and neutron distribution, proton and neutron radii of the even-even 124-208Sm (Z=62) isotopes were calculated in the framework of the HFB calculations with three different Skyrme type effective nucleon-nucleon interaction: SKI3, HFB9, UNE1 and Gogny force of type D1S. In view of existing different type of models and interactions, the question remains which of them provide the best description of data. Our calculated values were compared with the available experimental and theoretical results, where good agreements were obtained. | ||||
