This research represents the continuation of a set of extremely successful electron-scattering experiments in atomic hydrogen. The program uses techniques developed earlier for measurements of integral cross sections for electron-impact excitation to the H(2P) metastable state and the determination of the polarization of the subsequent Lyman-a radiation. Within this new period, the group will undertake to measure integral cross sections for excitation to the H(2S), H(3P), and H(4P) states and the polarization of the Lyman-a and Lyman-B radiation. New techniques will be developed to extract the fine structure contributions of individual angular momentum components of the n=3 and n=4 states.

这项研究代表了一系列非常成功的氢原子电子散射实验的继续。 该计划使用的技术开发较早的测量积分截面的电子碰撞激发H（2 P）亚稳态和随后的莱曼辐射的偏振的测定。 在这一新的时期内，该小组将着手测量激发到H（2S）、H（3 P）和H（4P）态的积分截面以及莱曼-a和莱曼-B辐射的偏振。 将开发新的技术来提取n=3和n=4状态的各个角动量分量的精细结构贡献。
