电子-核准弹性散射中的Pauli阻塞和末态相互作用

Pauli blocking and final-state interaction in electron-nucleus quasielastic scattering

Lon-chang, Liu

摘要:

研究了电子-核准弹性散射中的核子末态相互作用。基于散射波算符所满足的么正性方程,建立了一个考虑末态相互作用(包括核子敲出的泡利阻塞)的门道模型。该模型只使用实验形状因子作为输入,可以很容易地应用到轻和中等质量的核。在这些后者的核泡利阻塞效应的库仑相互作用的情况下说明。显着的影响,注意到低于350兆电子伏的光束能量和低动量转移。

英文摘要:

The nucleon final-state interaction in inclusive electron-nucleus quasielastic scattering is studied. Based on the unitarity equation satisfied by the scattering-wave operators, a doorway model is developed to take into account the final-state interaction including the Pauli blocking of nucleon knockout. The model uses only experimental form factors as the input and can be readily applied to light- and medium-mass nuclei. Pauli blocking effects in these latter nuclei are illustrated with the case of the Coulomb interaction. Significant effects are noted for beam energies below ~ 350 MeV and for low momentum transfers.
