无中子双β衰变的原子核结构

Nuclear Structure Aspects of Neutrinoless Double Beta Decay

B. A. Brown, M. Horoi, R. A. Sen'kov

摘要:

我们将无中微子双β衰变矩阵元分解为少两个核子的中间核上的乘积和。我们发现,对于轻中微子和重中微子衰变过程,和都是由中间核的J^pi=0^+基态决定的.这为比较和改进原子核结构模型提供了新的理论工具。它还提供了连接到两个核子转移实验。

英文摘要:

We decompose the neutrinoless double-beta decay matrix elements into sums of products over the intermediate nucleus with two less nucleons. We find that the sum is dominated by the J^pi=0^+ ground state of this intermediate nucleus for both the light and heavy neutrino decay processes. This provides a new theoretical tool for comparing and improving nuclear structure models. It also provides the connection to two-nucleon transfer experiments.
