This project focuses on the study of electron collisions with inert closed shell rare gases and molecular hydrogen (a closed-shell molecule). The first experiments address physics questions about the dynamics of electron-rare gas ionization particularly with regard to the collisional distribution of energy between the out-going ionized electrons. The project will focus on the difficult near-threshold ionization region where the energy of the two outgoing electrons is very low. Additional experiments will provide detailed electron collision data regarding the imparting of angular momentum by the scattering electron to the target, resulting in polarized radiation, in coincidence with the scattered electron. Extensive collaborations with theorists will assist comparisons between the experimental results and theoretical models. Important and broader impacts involve education of a large number of undergraduate and high school students as well as under-represented minority students. The present experimental group has, in the past 18 years, been active working with undergraduates and high school students and publishing papers with these students. Students are empowered to seek higher education in the form of PhD programs or seek employment in better positions in industry than they would have initially envisioned.

本项目主要研究电子与惰性闭壳层稀有气体和分子氢(闭壳层分子)的碰撞。第一个实验解决了有关电子-稀有气体电离动力学的物理问题，特别是关于外出电离电子之间的能量碰撞分配的问题。该项目将专注于困难的近阈值电离区，在那里，两个出射电子的能量非常低。其他实验将提供详细的电子碰撞数据，涉及散射电子给予目标的角动量，导致极化辐射，与散射电子一致。与理论家的广泛合作将有助于实验结果和理论模型之间的比较。重要和更广泛的影响涉及对大量本科生和高中生以及代表性不足的少数族裔学生的教育。在过去的18年里，本实验小组一直在积极地与本科生和高中生合作，并与这些学生一起发表论文。学生有权以博士项目的形式接受更高的教育，或者在行业中找到比他们最初设想的更好的职位。
