Atomic Collisions and Plasma Physics.
Abstract
Experimental studies have been carried out of ion-molecule interactions and reactions and electron-ion recombination reactions of interest in modelling the normal and disturbed regions of the earth's upper atmosphere. Drift tube and microwave afterglow techniques were employed for these studies. Rates of charge transfer, atom transfer and association in ion-molecule collisions involving both ground-state and metastable-state ions were determined at thermal energies for O(++), NO+, O2+, N+ and N2+ ions and He, O2, N2 and CO2 molecules. Mobility differentiation studies for ground state and metastable O+, O2+, O++ and O2++ ions moving in He or Ne gas were carried out. Recombination rates between electrons and CO+.CO, N2+.N2 (i.e., N4+) and O2+.O2 (I.e., O4+) ions were determined over a wide range of electron temperature. (Author)
