Abstract：
Recent years have witnessed intense activity concerning the study of nuclei with equal numbers of neutrons and protons (N=Z). Exotic properties have been exhibited in the N=Z nuclei, especially in those with atomic masses around 80. In the present paper, the projected shell model (PSM) together with a relativistic Hartree-Bogoliubov (RHB) theory is used to study the nuclear structure near the N=Z line in the mass A≈80 region. For three Zr isotopes ^80,82,84Zr, the projected potential energy surfaces and ground state bands are calculated. It is shown that shape coexistence occurs in all of these nuclei. Moreover, we find that the residual neutron-proton interaction strongly affects the ground state band of ⁸⁰Zr; however, it slightly modifies those of ⁸²Zr and ⁸⁴Zr.
