论文摘要
检查了核子核子短额相关性（SRC）对核超允许$β$衰减的影响。在$（e，e'）$和$（d，^3 {\ rm he}）$反应上，观察到的光谱强度的耗尽驱动了对此的需求。我们表明SRC的影响是模型依赖性的，但可能非常实质。 $^{46} $ v核被用作示例。讨论了对Cabibbo-Kobayashi-Maskawa（CKM）矩阵元素的单位性研究的影响。
The influence of nucleon-nucleon short-ranged correlations (SRC) on nuclear super-allowed $β$ decay is examined. The need for this is driven by the observed depletion of spectroscopic strength obtained in studies of $(e,e')$ and $(d,^3{\rm He})$ reactions on a wide variety of nuclei. We show that the influence of SRC is model-dependent, but may be very substantial. The $^{46}$V nucleus is used as an example. The resulting impact on studies of the unitarity of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element is discussed.
