NEMO-3 中 $^{100}$Mo 两中微子双贝塔衰变的详细研究
摘要：$^{100}$Mo双中微子双β衰变到$^{100}$Ru基态的半衰期的测量结果是$T\_{1/2} =\left[6.81\pm 0.01\left(\text{stat}\right)^{+0.38}_{-0.40}\left(\text{syst}\right)\right]\times10^{18}$年。我们提供了双电子能量之和、单电子能谱和电子之间夹角分布的统计量级为$5\times10^5$个事件和信噪比约为80的结果。对于这种核转变，我们发现了Single State Dominance模型的明确证据。我们获得了具有n=2、3、7的Majoron发射无中微子双β衰变模式的限制，以及对Lorentz不变性破坏和玻色型中微子在双中微子双β衰变模式中的贡献的约束。
