Abstract
A microscopic tight-binding cluster model is used to calculate the field-induced adsorption of He on tungsten. Likewise field evaporation of tungsten ions is computed as a function of electric field strength. The importance of local field effects - here taken from self-consistent jellium calculations - is emphasized.
