论文摘要
“ Ultra-low” Q值$β$衰减被称为其低衰减能量小于$ \ sim $ 1 keV。当父核腐烂到女儿的激发态时，其能量接近Q值的能量是可能的。这些衰减是中微子质量确定实验的潜在新候选者的感兴趣，也是研究原子干扰效应在核衰减过程中的测试基础。在本文中，我们提供了对原子质量数据和核能水平数据的更新评估，以识别潜在的超低Q值$β$衰减候选者。对于许多这些候选人，需要更精确，更准确的原子量数据来确定是否允许使用潜在的超低衰减分支的Q值，实际上是超低的。精确的原子质量测量可以通过PENNING TRAP质谱法实现。
"Ultra-low" Q value $β$ decays are referred to as such due to their low decay energies of less than $\sim$1 keV. Such a low energy decay is possible when the parent nucleus decays into an excited state in the daughter, with an energy close to that of the Q value. These decays are of interest as potential new candidates for neutrino mass determination experiments and as a testing ground for studies of atomic interference effects in the nuclear decay process. In this paper, we provide an updated evaluation of atomic mass data and nuclear energy level data to identify potential ultra-low Q value $β$ decay candidates. For many of these candidates, more precise and accurate atomic mass data is needed to determine if the Q value of the potential ultra-low decay branch is energetically allowed and in fact ultra-low. The precise atomic mass measurements can be achieved via Penning trap mass spectrometry.
