论文摘要
准粒子随机相近似（QRPA）用于评估参与双β衰变的最终核的总捕获率。使用该方法的几种变体，具体取决于所使用的单个粒子模型空间的大小或初始绑定的MUON波函数的处理。由此产生的捕获率彼此合理地相近。特别是，似乎最现实的变体导致速率与实验值吻合。无需进行轴向电流耦合常数$ g_a $的经验淬灭。其标准值$ g_a $ = 1.27似乎是足够的。
The Quasiparticle Random Phase Approximation (QRPA) is used in evaluation of the total muon capture ratesfor the final nuclei participating in double-beta decay. Several variants of the method are used, depending on the size of the single particle model space used, or treatment of the initial bound muon wave function. The resulting capture rates are all reasonably close to each other. In particular, the variant that appears to be most realistic, results in rates in good agreement with the experimental values. There is no necessity for an empirical quenching of the axial current coupling constant $g_A$. Its standard value $g_A$ = 1.27 seems to be adequate.
