在中国原子能科学研究院的HI-13串列加速器上,利用76Ge(37Cl,1p4n)108Cd重离子熔合蒸发反应布居了108Cd的yrast带高自旋态,采用瞬态场-离子注入扰动角分布(Transient-magnetic filed-ion implantation perturbed angular distribution,TMF-IMPAD)方法测量了108Cd的正宇称yrast带的g因子,测量得到2+、4+态g-因子分别为0.33(11)、0.18(6)。在10+态前后,发生h11/2中子顺排,g-因子值由正转负。从10+态到16+态,由于g7/2中子顺排,导致g-因子逐渐增大。测量得到反磁转动带带头16+态的g-因子为-0.09(3)。
At the HI-13 tandem accelerator of China Institute of Atomic Energy, the 108Ge heavy ion spin-elusion reaction was carried out using the 76Ge (37Cl, 1p4n) 108Cd heavy ion fusion evaporation reaction. The transient spinodal ion-implantation perturbation angle distribution (Transient (TMF-IMPAD) method was used to measure the g-factor of the positive parity yrast zone of 108Cd. The g-factors of 2 + and 4 + states were 0.33 (11) and 0.18 (6) . Before and after the 10+ state, h11 / 2 neutron tandem occurs and the g-factor value changes from positive to negative. From the 10+ state to the 16+ state, the g-factor is gradually increased due to the alignment of the g7 / 2 neutrons. The g-factor of the 16+ state in the head of the diamagnetic headband was measured to be -0.09 (3).
