丰中子核107Ru的集体转动带
Collective Bands in Neutron-Rich 107 Ru Nucleus
【摘要】 通过对2 5 2 Cf自发裂变产生的瞬发γ谱的测量 ,对丰中子奇A核10 7Ru的高自旋态集体转动带重新进行了研究 ,建立了新的能级纲图 .将基带转动带的自旋态扩展到 2 72 ,证实并扩展了以前发表的基于中子h11/2 激发产生的集体转动带 ,并新观测到一个基于 ( 9/ 2 - )能级的集体转动带 .研究结果澄清了早期发表的结果与近来别人发表的结果之间的矛盾 ,对新建立的10 7Ru能级结构的某些重要特征进行了讨论
【Abstract】 Through measuring prompt γ rays emitted in the spontaneous fission of 252 Cf with higher statistic data,level structures in the neutron rich,odd A 107 Ru nucleus have been re investigated. New level scheme of 107 Ru has been established. The ground state band was extended with spin up to 272 . The ν h 11/2 band structure observed in our previous publication has been confirmed and extended. These results clear up the inconsistence between our earlier work and results from another experiment published recently. A collective band built on (9/2 -) level has been observed for the first time. Some important features of the level scheme have been discussed.
