论文摘要
在Drukarev等人的早期工作之后，我们重新审视了改动和摇动作用在中微子双β衰变中的作用。我们发现与Drukarev等人一致。正如MEI和WEI最近所建议的那样，最终状态中的任何原子激发降低了衰减的Q值。我们讨论了随后的原子去激发射出的吸收如何将中性s中性双β衰变峰转移回其名义值。我们提出了对这些思想的原位实验验证，并讨论了改动和摇动对两种β衰变频谱形状的影响。
We revisit the role of shake-up and shake-off effects in neutrinoless double-beta decay, following earlier work by Drukarev et al. We find in agreement with Drukarev et al. that the Q value of the decay is reduced by any atomic excitation in the final-state but not by the difference in atomic binding energy of the initial and final state atoms, as was recently suggested by Mei and Wei. We discuss how the absorption of subsequent atomic de-excitation ejecta shifts the neutrinoless double-beta decay peak back to its nominal value. We propose an in situ experimental verification of these ideas, and discuss the impact of shake-up and shake-off on two-neutrino double-beta decay spectral shapes.
