概要

• 論文の詳細を見る

• We present microscopic calculations of the Interacting Boson Model (IBM) based on the shell model interaction by using the OAI mapping approach. We determine the collective pairs, which correspond to the IBM bosons, by the number conserved Hartree-Fock-Bogoluibov (HFB) and the proton-neutron Tamm-Dancoff methods, and we take into consideration couplings to the non-collective degrees of freedom. The present realistic calculations are carried out for the Te, Xe and Ba isotopes. Among them, the Xe isotopes are known by numerous phenomenological works to show the O(6) symmetry. We present the clear O(6) symmetry in the spectra and the wave function which are microscopically obtained.
