Abstract
We have measured de-excitation rays in populated by one-neutron stripping reactions with a target and 162-MeV , 162-MeV , and 120-MeV beams. rays in were identified by measuring kinetic energies of outgoing particles using Si detectors. It was demonstrated that high- orbitals were selectively populated in the (, ) reaction having a large negative value. We have observed eight quasiparticle states above the deformed shell gap of . The , , and bands were extended up to , , and states, respectively. We have established the state at 526 keV, the state with a short life of ps at 1030 keV, and the state with ns at 375 keV. Furthermore, the state, having a large component of the spherical single-particle state, has been identified at 1505 keV. We discuss the properties of those quasiparticle states in the framework of a deformed shell model.
