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.
