标题： Muon capture, continuum random phase approximation and in-medium renormalization of the axial-vector coupling constant

摘要： 我们使用连续随机相位近似来描述μ子在C-12、O-16和Ca-40上的捕获。 我们使用自由核子弱形式因子和两种不同的剩余相互作用，将这些核的实验总捕获率再现得优于10%。 然而，如果采用中介质中轴矢耦合常数的淬灭，则对于相同的剩余相互作用，计算得到的速率显著低于数据。 显示英文摘要

摘要： We use the continuum random phase approximation to describe the muon capture on C-12, O-16 and Ca-40. We reproduce the experimental total capture rates on these nuclei to better than 10% using the free nucleon weak form factors and two different residual interactions. However, the calculated rates for the same residual interactions are significantly lower than the data if the in-medium quenching of the axial-vector coupling constant is employed.
