文摘

The g-factors of the rotational states of the positive parity yrast band from spin I=10 + to spin I=16 + in even-even nucleus 108Cd have been measured by the transient-magnetic-field ion implantation perturbed angular distribution method. The high spin states of 108Cd were populated by the fusion evaporation reaction 76Ge (37Cl, 1p4n) 108Cd. The measured g-factors increase gradually as the spin increases from 10 + to 16 + due to the g 7/2 neutron alignment. The g 7/2 neutrons are fully aligned at spin I=16+. This state is the band head state of the anti-magnetic rotational band in 108Cd. The measured g-factor of this state is -0.09. The present results support that this band head state may have the configuration \(\pi (g_{9/2})^{-2}_{J=0}\otimes \nu (h_{11/2})^{2}_{J=10}\nu (g_{7/2})^{2}_{J=6}\) .
