Study in Molecular Lasers.

Abstract

Abstract : Principal progress was achieved in the field classical studies of diatom dissociation. 3-D trajectory calculations of dissociating bromine and fluorine were conducted over a range of temperatures, and using several significantly different potential energy surfaces. A library consisting over a two million trajectories was accummulated. These trajectories were used to test the strong collision assumption, important in several theories of unimolecular reactions and in some theories of thermal diatom dissociation. The assumption was shown to be not valid for the case of dissociating bromine and fluorine. Properties of the steady state of dissociating diatoms were investigated. Papers, now in preparation, involve study of nonequilibrium energy and angular momentum distribution functions; accumulation, interpretation and classification of data on inelastic and reactive collisions; and study of scaling factors and vibrational-rotational coupling in dissociating diatoms. Experiments, still in progress, aimed at measuring recombination rates of fluorine atoms. Time delayed photoelectric effect was explained in terms of a release of trapped electrons at the surface of photocathode.
