Abstract : Some investigations are carried over from the first report No. AF61(052)-299 and also some new investigations are reported. Chapters 3, 4 and 5 complete the investigations on the effects of vertical diffusion and drift in the F2 region. Chapters 1 and 2 deal with the effect of the geomagnetic field on diffusion in the F2 region near the geomagnetic equator. Chapter 6 is a recently completed extension of this investigation to estimate the importance of electrodynamic drift. Finally, Chapter 7 indicates a convenient way of calculating the distribution of hydrogen and helium ions in the exosphere on the assumption of thermodynamic equilibrium. (Author)
