论文摘要
传统上，双中性s电子捕获被认为是共振过程。在$^{164} $ er的情况下，我们已经实现了摇动概率计算，导致电子外壳电离。摇动的津贴消除了共振的要求，从而增加了捕获率。与常规共振荧光机制相比，新机制的贡献使捕获率提高了5.6倍。它还增加了从较高壳中捕获电子的可能性，这在一项实验研究中必须预见。此外，摇动的效果可能会扩大实验的候选核列表。
Traditionally double neutrinoless electronic capture is considered as a resonance process. We have fulfilled shake-off probability calculations, leading to ionization of the electron shell, in the case of $^{164}$Er. Allowance for the shake-off removes the requirement of resonance, leading to an increase of the capture rate. The contribution of the new mechanism increases the capture rate by a factor of 5.6 compared to the conventional resonance fluorescence mechanism. It also increases the probability of electron capture from higher shells, which must be foreseen in an experimental study. Moreover, effect of the shake-off can potentially expand the list of candidate nuclei for experiments.
