Abstract : Quantal investigations have been carried out on the following: the average excitation energy of an atom or molecule appropriate to the slowing down of a beam of charged particles in a gas; the long-range interactions between pairs of atoms and also between three hydrogen atoms; various atomic structural problems including the polarization of a closed shell core by an outer electron, relativistic corrections to the eigenenergies for the helium sequence, correlation energies of the lithium sequence, isotope shifts in Li and B(2+). Theoretical studies have been made of the following upper atmospheric problems: the source, abundance and distribution of each of hydrogen, metastable helium and nitrous oxide; the electron temperature in the D-region; the diurnal variation of the temperature and density (assuming solar ultra-violet heating); the Doppler profiles of the 5577 A airglow.
