论文摘要
传统上，双中性s电子捕获被认为是共振过程。在164ER的情况下，我们实现了摇动概率计算，导致电子壳的电离。摇动的津贴消除了共振的要求，从而导致捕获率的根本提高。在164er的情况下，与常规的共振荧光机理相比，新机制的贡献将捕获率提高了5.6。它还增加了从较高壳中捕获电子的可能性，这在实验研究中必须预见。此外，摇动的效果可以扩大实验研究的候选核列表。摇动的影响还有望在其他β过程中表现出来，这些过程中中微子的研究，其质量和在暗物质难题中的作用。
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.
