RUI: Electron Impact Ionization of Argon and Krypton and Excitation of Resonance Transitions in Neon, Xenon and Molecular Hydrogen.

加州州立大学富勒顿分校实验低能电子碰撞小组的项目目前专注于研究电子与惰性稀有气体（氖、氩、氪和氙）和分子氢（也是闭壳分子）的碰撞。去年，稀有气体靶（特别是氖气和氙气）的电子碰撞电离动力学揭示了一些非常有趣的结果。这些结果表明，对于氖，在特定散射情况下的近阈值电离区域（前向散射以及两个出射电子中的任何一个的能量非常低），该过程似乎受到被吸入极化离子核的电子的抑制。该小组针对这种效应提出了一个有趣的假设。目前，它正在更深入地研究这种机制，用氩和氪进行类似的实验，未来的第二系列实验希望提供有关散射电子向稀有气体目标或分子氢与散射电子一致的角动量传递的详细信息，特别是测试后向散射角附近大角散射的最新理论。加州州立大学富勒顿分校的实验低能电子碰撞小组是一个非常活跃的小组，几乎有一半物理系专业的学生参与研究。该小组还拥有本科生作者在顶级同行评审期刊上发表论文的良好记录。该项目培养的博士生数量远远多于该系的任何其他项目。更广泛的影响还涉及大量高中生以及代表性不足的女性和少数族裔学生的教育（加州州立富勒顿分校是国家认可的西班牙裔服务学院）。

The program of the experimental low energy electron collisions group at California State University Fullerton is currently focused on the study of electron collisions with inert rare gases (neon, argon, krypton and xenon) and molecular hydrogen (also a closed shell molecule). The dynamics of electron impact ionization of the rare gas target (specifically neon and xenon) revealed some very interesting results last year. These showed for neon that in the near-threshold ionization region in specific scattering cases (forward scattering and where the energy of either of the two outgoing electrons was very low), the process seems to be inhibited by the electron being sucked into the polarized ion-core. The group has proposed an interesting hypothesis for this effect. Presently it is delving deeper into such mechanisms, with similar experiments with argon and krypton, A second series of experiments in the future hopes to provide detailed information regarding the imparting of angular momentum by the scattering electron to the rare gas target or molecular hydrogen in coincidence with the scattered electron, especially to test state-of-art theories for large angle scattering near backward scattering angles. The experimental low energy electron collisions group at California State University Fullerton is a very active group, where almost half of the physics department's majors participate in research. The group also has a strong publication record with undergraduate student authors on papers in top peer-reviewed journals. The program generates by far more PhD-bound students than any other program in the department. Broader impacts also involve education of a significant number of high school students as well as under-represented women and minority students (California State Fullerton is a nationally recognized Hispanic serving college).
