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^175Er、^197Os、^229Ra、^238Th和^186mTa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.
