分离鉴别重丰中子核的重要手段：X-γ符合技术

Important Means for Separating and Identifying Heavy Neutron-rich Nuclides:X-γcoincidence technique

本文简单地介绍远离β-稳定线重质量丰中子核的合成和研究的科学意义。扼要叙述X-γ符合技术(元素指定方法)。指出X-γ符合方法在远离β-稳定线重丰中子核研究中的重要作用。借助于X-γ方法先后研究了一些如^(175)Er、^(197)Os、^(229)Ra、^(238)Th和^(186m)Ta等重丰中子核。

The significance of the synthesis and study of heavy-mass, neutron-rich nuclides far from βstability is simply introduced. The X-γ coincidence technique （element assignment method） are essentialized. The important role of X-γ coincidence method for study of heavy neutron-rlch nuclides far from β- stability is pointed out. Some heavy neutron-rich nuclides such as ^175Er, ^197Os, ^229Ra, ^238Th, and ^186raTa were successively studied by means of X-γ coincidence method.
