This RUI activity focuses on the experimental determination of more precise values of the differential cross-section ratio for electron scattering from neon, argon, krypton, and xenon atoms for scattering angles from 0-180 degrees. Also measured will be the experimentally-normalized doubly-differential cross-sections for near-threshold electron-impact ionization of helium, neon, argon, krypton, and xenon for scattering angles of 5-130 degrees. The broader impacts relate to the education of undergraduate students at this RUI institution.

这项RUI活动集中在从0-180度的散射角范围内更精确地确定电子与Ne、Ar、氪和Xe原子的散射的微分截面比的实验值。还将测量在5-130度的散射角下氦、氦、氩、氪和氙气的近阈值电子碰撞电离的实验归一化双差分截面。更广泛的影响与这所瑞学院本科生的教育有关。
