✦ Synopsis
The charge transfer reaction of He+ with N20 produces vibrationally excited N:(X) ions. The relaxation processes occurring after formation of the NC (X, u" ) ions have been investigated. Charge transfer with N,O is the main relaxation mechanism and its rate does not vary much with the internal energy of N: Analysis of the energy disposal in the He+/N>O charge transfer indicate that multiple excitation states ofN,O, nearly resonant with the recombination energy of He+ are most certainly implied in the charge transfer.
