反动力学下的$^{82}$Kr(p,$\gamma$)$^{83}$Rb反应截面测量
摘要:首次在有效的质心能量为2.4至3.0 MeV之间测量了$ ^{82} $Kr (p,$ \gamma $) $ ^{83} $Rb反应的总截面,在天体物理学中相关的Gamow窗口内。实验在密歇根州立大学的国家超导环实验室的ReA设施进行。将$ ^{82} $Kr束流定向到位于Summing NaI(Tl) (SuN)探测器中心的氢气体池中。使用$ \gamma $-summ化技术分析了获得的光谱,并将提取的截面与使用non-smoker和talys代码的标准统计模型计算进行了比较。比较表明,相对于实验测量值,标准统计模型计算倾向于高估$ ^{82} $Kr(p,$ \gamma $)$ ^{83} $Rb反应的截面。此外,利用实验数据进一步限制了统计模型计算中使用的核子能级密度和$ \gamma $射线强度函数。
