The spontaneous fission is primary factor restricting numbers of transuranium elements.
超铀元素的存在受到诸多因素的限制，而自发裂变是限制超铀元素数目的最主要因素，从自发裂变限制方面分析，超铀元素的存在界限大体在Ｚ＝１２０号元素以内。
Through measuring high-fold prompt γ- ray coincidence events following the spontaneous fission of 252 Cf with the Gammasphere detector array, new level scheme in the very neutron-rich odd-A 113Ru nucleus has been established.
通过对重核~(252)Cf自发裂变产生的瞬发γ谱的测量,对非常丰中子核~(113)Ru的能级结构进行了研究,建立了较高自旋态的能级纲图,识别了基于中子h_(11/2)轨道激发产生的集体转动带,最高自旋态达31/2h。
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.
