Abstract

In this work we report on studies of the kinetics of He-N2 mixtures excited by a proton beam. The rate of charge transfer from both atomic and molecular helium ions to N2 was studied using a time-resolved technique to measure the fluorescence of N2+ (B 2Σu+→X2Σ g). The population of N2+(B 2Σu+) through a Penning ionization process from metastable helium atoms or molecules is observed, and the Penning ionization and charge transfer process which populates this state in a He-N 2 laser is discussed. The charge transfer rate constants of He +-CO, He+-CO2, He+-H2S, and He2+-CO are also measured.
