对来自100Mo的两条β射线的光谱研究，对于用无中微子双β衰变(0nubetabeta)研究Majorana nu质量和用逆β衰变研究低能太阳nu都有潜在的意义。用一台多吨100Mo探测器，与大Q值(Q(Betabeta))符合研究，可以识别灵敏度约为0.03 eV的核质量项。对100Tc的逆贝塔衰变和逐次贝塔衰变的相关研究，再加上对低能量太阳NU的大捕获率，使得在同一探测器中实时探测单个低能量太阳NU成为可能。
Spectroscopic studies of two beta rays from 100Mo are shown to be of potential interest for investigating both the Majorana nu mass by neutrinoless double beta decay (0nubetabeta) and low energy solar nu's by inverse beta decay. With a multiton 100Mo detector, coincidence studies of correlated betabeta from 0nubetabeta, together with the large Q value ( Q(betabeta)), permit identification of the nu-mass term with a sensitivity of approximately 0.03 eV. Correlation studies of the inverse beta decay and the successive beta decay of 100Tc, together with the large capture rates for low energy solar nu's, make it possible to detect, in real time, individual low energy solar nu in the same detector.
