        Effects of the Pairing Interactions among the Nucleons in Exotic Nuclei within the Hartree Fock Bogoliubob (HFB) Theory

        천명기,Fedor Simkovic,Amand Faessler 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.2

        We investigated the effects of nucleon pairing interactions, which include like nucleon pairing (neutron-neutron and proton-proton pairing) and unlike nucleon pairing (neutron-proton) interac- tions, on nuclear structure. In specic, the importance of the unlike pairing is detailed in medium heavy nuclei, such as isotopes of Ge and Zr. Al calculations are carried out within the Hartree Fock Bogoliubob theory in the Nilson basis in order to consider the deformation of the nuclei, which is a typical phenomenon in the exotic nuclei relevant to nucleosynthesis. Our results show that the unlike pairing interactions could play vital roles in understanding the nuclear structure. Even the ordinary nuclei, which are not usualy expected to have such large unlike proton pairing interac- tions, because of large Fermi energy gaps between protons and neutrons, could have unlike pairing interactions strong enough to be deliberately included. Our results are applied to the 64-76Ge and the 80-100Zr isotope series, which nuclei have recently been exploited as important isotopes in the rapid proton process in nucleosynthesis.
