摘 要：Recent years have witnessed an 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 mass around *** 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 *** three Zr isotopes Zr,ground state deformations are determined in the RHB theory, and the projected potential energy surfaces and ground state bands are calculated applying the PSM. Shape coexistence occurs in all of these nuclei,and a pronounced superdeformation exists in Zr. These results are in good agreement with experiments and other theoretical ***,we
