g-factors measurement of magnetic rotation band in 85Zr

摘要：

The magnetic-rotational band in 85Zr was populated by the fusion-evaporation reaction 60Ni(28Si,2pn)85Zr with a 98 MeV Si beam from the HI-13 tandem accelerator at China Institute of Atomic Energy.The g-factors of the high spin states of this magnetic rotation band in 85Zr were measured by the TMF-IMPAD method for the first time.The measured g-factors decrease with the increasing of spin.It implies that the valence neutron alignment is more rapid than that of the valence proton,which leads to a decrease of g-factors along the band.
