Second-Kind Collisions Between Electrons and Mercury Atoms in the 6 triplet P(0) and 6 triplet P(2) Metastable Levels

摘要

The differential cross sections for inelastic second-kind collisions were measured for 2.4-eV electrons scattered from the 6 triplet P(0) and 6 triplet P92) metastable levels of mercury. Separation of the scattering from the two levels was achieved. The energy dependence of the differential cross sections was measured for 0.5-to-5.0-eV electrons. The angular dependence of the differential cross sections was measured for 2.0-eV electrons. Comparisons between experimental and theoretical results were made in all cases. The excited mercury levels were obtained through a two-stage optical pumping technique. (Author)
