摘　　要：通过重离子融合蒸发反应16 O(82 Se +4n) 94 Mo布局了94 Mo核的高自旋态 .利用多探头探测器阵列GASP进行了在束γ测量 ,从而重新研究了94 Mo核的高自旋态能级结构 .基于新发现的一些重要的连接跃迁 ,对94 Mo核的高自旋态能级纲图做了重要修改 .将新的能级结构与壳模型计算进行了比较和讨论 .结果表明要正确的描述94 Mo核的高自旋态 (自旋值大于 14 )能级结构 ,应考虑价中子在d5/ 2 ,g7/ 2 和h11/ 2 轨道上的激发 .High-spin level structure of 94Mo has been re-investigated using the modern multidetector array of GASP via the 16O( 82Se,4nγ) 94Mo reaction at E( 82Se)=459 MeV.The previously reported level scheme has been largely modified up to ～10 MeV in excitation energy due to identifications of some important linking transitions.The level structure of 94Mo has been compared with the shell model calculations.It is suggested that the valence neutron excitation within d 5/2,g 7/2,and h 11/2 orbitals should be taken into account in order to adequately describe the high-spin level structure of 94Mo above Iπ=14+.
