This thesis is a computer simulation of secondary electronemission (SEE) from monocrystalline metals and alkali-halidesusing a modified version of the Harrison, Carlston and Magnusonsingle collision theory of SEE. Three cases of SEE are investigated: the angular dependence of SEE from Cu bombarded by Ar ,the dependence of SEE as a function of energy for rare gas ionsnormally incident on the (100) , (110) and (111) faces ofmetal single crystals, and the dependence of SEE as a functionof energy for Ar and Ne ions normally incident on the (100) ,(110) and (111) faces of KC1. The theory does not accuratelydescribe the angular dependence of SEE for monocrystalline Cutargets, but does accurately predict the modified sec 6 dependencefound experimentally in polycrystalline studies. Forthe metal targets, the difference between the theoreticalkinetic secondary emission result and the experimental datumis identified as potential secondary emission. The alkalihalideSEE simulation agrees reasonably well with experiment.
