Abstract
The effects of temperature and hydrogen density on the efficiency of production of H3* Rydberg levels in a hollow cathode discharge are determined by monitoring the 3s2A1′→2p 2A2″ transition of H3*. Kinetic modeling of the ion-molecule reactions occurring in the discharge indicates that the observed H3* spectral intensity dependence on discharge temperature and density can be accounted for if it is assumed that H 5+/e- dissociative recombination is the primary process leading to H3* formation. The previously observed extensive Doppler-like broadening of the H3* emission lines is explained in terms of the dissociative kinetic energy release of H 5**.
