RESEARCH IN NON-EQUILIBRIUM RADIATIVE PROCESSES.

Abstract

The primary objective has been to investigate, or develop improved means for investigating, phenomena of interest to a basic understanding of certain aspects of the aerospace environment, particularly those involving optical emissions. The central approach to the attainment of this objective has been by laboratory-based studies of the mechanisms responsible for the radiative phenomena. The purpose of the effort has been to improve our understanding of the basic atomic and molecular processes in the hope that eventually related macroscopic atmospheric properties, directly applicable to Air Force problems, can be reliably predicted. Phenomena which have been investigated in the laboratory include vibrational relaxation in pure gases and in gas mixtures and excitation in collisions of energetic ions and neutrals with low-pressure targets of atmospheric gases. The variations in the intensity of OH emissions from the night sky have been studied. The development of a high-intensity supersonic nozzle beam for use in the study of problems of interest in chemical physics has been pursued. (Author)
