标题： Polarization observables in electronuclear two-nucleon knockout

摘要： 目前，（e,e'pp）微分测量被认为是研究有限原子核中短程关联的一种方法。 研究了（$\vec{e},e'\vec{p}p$）和（$\vec{e},e'\vec{p}n$）的微分截面与极化可观测量，所用的是一个能描述短程关联、出射核子畸变、介子交换以及 $\Delta$- 异位子电流的微观模型。 指出极化可观测量代表了一种绝对电子核两核击出测量的有吸引力的替代方案。 在（$\vec{e},e'\vec{p}p$）的极化传递 $P'_t$ 中，预测中心短程关联的效果较大，而同时最终状态相互作用的影响较小。 显示英文摘要

摘要： Differential (e,e'pp) measurements are presently recognized as a way of studying short-range correlations in finite nuclei. The ($\vec{e},e'\vec{p}p$) and ($\vec{e},e'\vec{p}n$) differential cross section and polarization observables are studied in a microscopic model that accounts for the short-range correlations, outgoing-nucleon distortions, meson-exchange and $\Delta$-isobar currents. It is pointed out that polarization observables represent an attractive alternative for absolute electronuclear two-nucleon knockout measurements. In the polarization transfer $P'_t$ for ($\vec{e},e'\vec{p}p$), the effect of central short-range correlations is predicted to be large while at the same time the final-state interaction effects are small.
