中文摘要：

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）。

英文摘要：

Background： The interplay between the collective rotation and the quasi-particle alignment is a significant feature of nuclear structure at high spins. The g-factors of intra-band high spin states of the ground rotational band can provide direct and unique information on quasi-particle alignment since the g-factors of the high-j proton and the high-j neutron are positively large and negatively small, respectively. Purpose： The present work was motivated to measure g-factors of the rotational states of the positive parity yrast band in ^108Cd and to study the quasi-particle alignment. Methods： High spin states of ^108Cd were populated by the fusion-evaporation reaction ^76Ge（^37Cl, 1p4n）^18Cd at beam energy of 135 MeV from the HI-13 tandem accelerator at China Institute of Atomic Energy, and the g-factors were determined by the transient-magnetic filed-ion implantation perturbed angular distribution （TMF-IMPAD） method. Results： The measured g-factors of 2^＋, 4^＋ state are 0.33（11）, 0.18（6）, respectively. The h11/2 neutrons align at the 10＋ state, which leads to the decrement of the g-factors. And the g7/2 neutrons align gradually from 10^＋ to 16^＋, which makes the g-factors increase, Conclusion： The g-factor of the bend head of the anti-magnetic rotation band, 16^＋ state, was measured and the value is -0.09（3）.
