论文摘要

在Jefferson Lab Hall A中进行的E12-14-012实验已使用天然氩气和天然钛靶标在平行的运动学中收集了独家电子散布数据（E，E $^\ prime $ P）。在这里，我们报告了对应于2,222 MeV的束能，电子散射角21.5度和质子发射角-50度的数据集的第一个结果。以$ \ sim $ 4％的不确定性测量的差分横截面已被研究为缺失能量和缺失动量的函数，并与基于扭曲的波浪脉冲近似模型获得的蒙特卡洛模拟的结果进行了比较。

The E12-14-012 experiment, performed in Jefferson Lab Hall A, has collected exclusive electron-scattering data (e,e$^\prime$p) in parallel kinematics using natural argon and natural titanium targets. Here, we report the first results of the analysis of the data set corresponding to beam energy of 2,222 MeV, electron scattering angle 21.5 deg, and proton emission angle -50 deg. The differential cross sections, measured with $\sim$4% uncertainty, have been studied as a function of missing energy and missing momentum, and compared to the results of Monte Carlo simulations, obtained from a model based on the Distorted Wave Impulse Approximation.
