252 Cf核团簇衰变中探测八中子的争论
Arguments for Detecting Octaneutrons in Cluster Decay of 252Cf Nuclei
摘要：
介绍并实现了一种寻找由核力束缚的中子组成的中子团簇（多中子）的新方法。该方法是基于对子核的搜索出现在252 Cf的核簇衰变到中子簇。利用了具有高原子序数和长半衰期的子核的长时间积累的效果。结果发现Cf-252衰变为子核U-232（半衰期T1/2= 68.9年）。据推测，U-232核的出现归因于由八个中子-八中子组成的中子团簇的发射。八中子的发射几率与Cf-252的α衰变几率之比为λC/λα = 1.74*10-6。
英文摘要：
A new method of searching for neutron clusters (multineutrons) composed of neutrons bound by nuclear forces has been introduced and implemented. The method is based on the search for daughter nuclei that emerge at the nuclei cluster decay of 252Cf to neutron clusters. The effect of long-time build-up of daughter nuclei with a high atomic number and long half-life was utilized. As a result, the cluster decay of Cf-252 to a daughter nucleus U-232 (half- life of T1/2= 68.9 years) was discovered. It is assumed that the emergence of U-232 nuclei is attributed to emission of neutron clusters consisting of eight neutrons - octaneutrons. The emission probability of octaneutrons against α-decay probability of Cf-252 is defined equal to λC/λα = 1.74*10-6.
