摘　　要：采用裂变产物-γ-γ符合法,对^(252)Cf裂变瞬发γ谱进行了研究,扩展了A～100及150区的30种丰中子偶-偶核素的能级结构,最高自旋可达10～14.对某些同位素链的核结构及形状相变特性进行了讨论.Level structures of neutron-rich even-even nuclei around A～100 and 150 regions have been studied by observing the prompt gamma rays from the spontaneous fission of ^(252)Cf. The highest spin is up to 10～14. The character of nuclear structures and shape phase transitions of some isotope chains are discussed.
