Abstract:

This project deals with electron impact experiments on atoms and molecules relevant to the development of the N2-CO2 and rare-gas halide lasers. Cross sections for state-of-state transitions in a variety of collisional processes rotational, vibrational, and electronic excitation dissociative attachment have been determined in the first 4 eV of threshold and are generally found to exhibit great enhancement attributable to resonances. Highlights of the methods of cross-section measurement are also presented.
