【Abstract】 Recently,the study of 40 Z45,A ～90 neutron deficient nuclei shows that when the number of neutrons changes from N 47 to N <46,the nuclear structure will transits from shell model to collective mode.The structure of N=47 neutron deficient nuclei 92 Rh is a very interesting subject. So far the only information about the property of 92 Rh is the lower limit of its half life and the in beam γ ray spectrum.By means of beam chopping and γ γ spectroscopy of the 40 Ca+ 58 Ni reaction products,the decay γ rays of 92 Rh have been identified for the first time. The spin and parity of the ground state has been deduced.更多还原
