摘要：

Emission from chlorine ions in helium discharges is intense and cannot be explained on the basis of Boltzmann and Saha considerations alone. Presented is a study which reconciles observed ion emission based upon charge-transfer ionization-excitation of ground state chlorine atoms by helium ions. The 3s3p5 3P(o) chlorine ion state populated by this reaction serves as a reservoir to populate nearby electronic states which are involved in the observed emission. This model explains why intense chlorine ion emission is observed in helium discharges, but not in those of argon.
