Abstract : It is found that the 'spot size' formed by fast metal atoms released at altitudes above 200 km is dominated at practically all pitch angles by by a charge changing diffusion away from the field line of release. The author has derived a diffusion coefficient for charge changing diffusion of multi-charge state systems of which a metal atom is a particular example. This diffusion coefficient has been applied to predicting the 'spot size'. Good agreement has been obtained between predicted 'spot sizes' and those obtained from Monte Carlo calculations.
