通过96 Ru( 4 0 Ca ,ln2p)反应 ,采用氦喷嘴带传输系统和X γ与γ γ符合测量方法 ,首次建议了133Sm的简单的 (EC + β+)衰变纲图 .由于Ru靶中含有98— 10 2 Ru的成分 ,同时产生了133Pr,并首次测定了133Pr的 1 1 / 2 - 同质异能态的寿命为( 1 .1± 0 .2 )s.用单粒子模型提取了131,133,135 ,137Pr的 1 1 / 2 - 同质异能态的约化跃迁几率的实验值 ,并与Weisscopf近似估计进行了比较 . The simple (EC + β +) decay scheme of 133Sm was proposed for the first time by the 96 Ru (4 0 Ca, ln2p) reaction, the helium nozzle with transmission system and the γ γ and γ γ coincidence measurement methods. 98- 10 2 Ru, 133Pr was simultaneously produced, and the lifetime of the 1 1/2-isomorphic state of 133Pr was first determined to be (1.1 ± 0.2) s. The single particle model was used to extract 131,133,135 , 137Pr 1 1/2 - isomorphism of the reduced transition probability of experimental values, and Weisscopf approximate estimates were compared.
