Abstract:

Investigations directly concerned with the upper atmosphere include Theoretical studies of dirunal variation of the temperature of the thermosphere and Observational studies of the following temperature of OI atoms responsible for the 6300 A emission of the nightglow, the 6300 A OI dayglow emission, variations of hydroxyl and oxygen emissions in the infra-red airglow, infra-red investigations of the night sky using a Michelson interferometer, and all-sky interferometer for airglow studies. Fundamental quantal calculations of collisional processes and atomic structural problems are also examined Collisional processes include Calculations of scattering cross sections using the first and second Born approximations, impact ionization cross sections, and photoionization cross sections of molecular hydrogen. Atomic structural problems include Semi-empirical effective potentials for use in atomic, molecular and solid-state problems three-electron systems, and long range forces between pairs of atoms.
