论文摘要
我们研究了核系统对两体分布的含义，并得出了给定核的不同密度或动量分布之间的关系或在同一isospin多重组中的不同核的动量分布。还获得了镜子核的中性双β衰变过渡与两体密度之间的联系。通过量子蒙特卡洛计算，在数值上验证了关系。我们讨论了这些结果与核短距离相关性分析的相关性，还表明，当形成短距离相关对时，同源对称性使我们能够提取有关观众核子的信息。
We study the implications of isospin symmetry in nuclear systems on two-body distributions and derive relations between different densities or momentum distributions of a given nucleus or of different nuclei in the same isospin multiplet. A connection between neutrinoless double beta decay transition of mirror nuclei and two-body densities is also obtained. The relations are numerically verified by means of quantum Monte Carlo calculations. We discuss the relevance of these results to the analysis of nuclear short-range correlations and also show that isospin symmetry allows us to extract information about the spectator nucleons when a short-range correlated pair is formed.
