通过58 Ni(40 Ca ,3n2p)反应合成等待点核93 Pd ,采用氦喷嘴带传输系统加p γ符合 ,观测到了它的 β缓发质子衰变 ,测得其半衰期为 (1.3± 0 .2 )s .采用统计模型计算拟合了实验测得的 β缓发质子能谱和布居到质子发射体子核不同终态的分支比 ,指认了93 Pd的基态自旋为 9 2 .用Woods XasonStrutinsky方法计算了93 Pd的核位能面 ,其结果表明93 Pd基态自旋宇称可能为 9 2 + .
The 58 Pd (40 Ca, 3n2p) reaction was used to prepare 93 Pd, and the β-delayed proton decay was observed using a helium nozzle with transmission system plus p γ. The half-life was measured as (1.3 ± 0.2) s. The statistical model was used to fit the experimentally measured β-delayed proton energy spectra and the branching ratios to different end-states of the proton emitter nucleus, which indicated that the ground state spin of 93 Pd was 92. Using the Woods Xason Strutinsky method The nucleus energy surface of 93 Pd has been calculated and the results show that the ground state spin of 93 Pd may be 9 2 +.
