Collisional Energy Transfer and Topics Related to the Gas Laser Mechanism.

Abstract

Through the two year period of the grant the work done represented important steps in the theory of energy transfer during molecular collisions and the theory of collision-induced absorption. Experimental work included measurement of the rates and temperature dependencies for near-resonant transfer processes in several systems. These results were explained by the appropriate theoretical methods using long-range multipolar interactions and the distorted-wave first-order Born approximation. Collision-induced absorption coefficients in rare gas mixtures were also calculated. Eight journal publications resulted from this research.
