摘要：
传统上，无中微子双电子俘获被视为一种共振过程。我们针对164Er完成了会导致电子壳层电离的shake-off（震脱）概率计算。考虑震脱效应后，不再需要满足共振条件，从而使俘获率大幅提升。在164Er的情况中，与传统的共振荧光机制相比，这种新机制的贡献使俘获率提升了5.6倍。它还提高了从更高壳层俘获电子的概率，这一点在实验研究中必须预先考虑。此外，震脱效应可以扩大实验研究的候选原子核列表。预计震脱效应的影响还会体现在其他用于研究中微子性质、中微子质量及其在暗物质谜题中作用的β过程中。
英文摘要：
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 164Er. Allowance for the shake-off removes the requirement of resonance, leading to a radical increase of the capture rate. In the case of 164Er, the contribution of the new mechanism increases the capture rate by a factor of 5.6 as compared to the conventional resonance fluorescence mechanism. It also increases the probability of electron capture from higher shells, which must be foreseen in the experimental studies. Moreover, the effect of the shake-off can expand the list of candidate nuclei for experimental research. The influence of the shake-off is also expected to manifest itself in the other beta processes which are used in the studies of the neutrino nature, its mass and role in the dark matter puzzle.
