Abstract
High-spin level structures of the near-spherical nuclei Zr have been reinvestigated via the Se(C, ) reactions at a beam energy of 44 MeV. By the use of in-beam spectroscopic methods, 13 new transitions belonging to Zr and 19 to Zr have been observed and the level schemes of Zr have been extended up to 11 MeV excitation energy. The newly constructed level schemes are characterized by the Sr core breaking, and the proton energy gap in Zr is obviously reduced compared with Zr when one more neutron goes into the orbital.
