通过测量与101 MeV氚的反应截面，确定了和的无中微子双衰变过程中初态和终态之间的价质子组态的变化。连同我们最近对过程中涉及的相关中子组态的确定，与最新的壳层模型和相互作用玻色子模型计算的定量比较显示出显著的差异。这些都是用来确定控制这些系统中无中微子双衰变速率的核矩阵元素的相同计算。
The change in the configuration of valence protons between the initial and final states in the neutrinoless double-decay ofand ofhas been determined by measuring the cross sections of thereaction with 101-MeV deuterons. Together with our recent determination of the relevant neutron configurations involved in the process, a quantitative comparison with the latest shell-model and interacting-boson-model calculations reveals significant discrepancies. These are the same calculations used to determine the nuclear matrix elements governing the rate of neutrinoless double-decay in these systems.
