标题： Effects of Short-Range Correlations in (e,e'p) reactions and nuclear overlap functions

摘要： 对闭壳核在低缺失能量下短程关联对（e,e'p）反应的影响进行研究。 我们使用从单体密度矩阵的渐近行为中提取的关联准-hole重叠函数，其中包含Jastrow型的中心关联，至簇展开的一阶，并在非常高的渐近区域计算，达到100 fm。 在简单的壳模型中检查了提取重叠函数的方法，其中精确结果是已知的。 我们发现由于核芯的短程排斥，价壳的单粒子波函数向右移动。 相对于壳模型，相应的谱学因子仅减少了几个百分点。 然而，由于短程关联，在缺失动量分布的最大值区域，（e,e'p）响应函数和截面得到增强。 显示英文摘要

摘要： A study of the effects of short-range correlations over the (e,e'p) reaction for low missing energy in closed shell nuclei is presented. We use correlated, quasi-hole overlap functions extracted from the asymptotic behavior of the one-body density matrix, containing central correlations of Jastrow type, up to first-order in a cluster expansion, and computed in the very high asymptotic region, up to 100 fm. The method to extract the overlap functions is checked in a simple shell model, where the exact results are known. We find that the single-particle wave functions of the valence shells are shifted to the right due to the short-range repulsion by the nuclear core. The corresponding spectroscopic factors are reduced only a few percent with respect to the shell model. However, the (e,e'p) response functions and cross sections are enhanced in the region of the maximum of the missing momentum distribution due to short-range correlations.
