The impurities which are used in the calculations are Na, Cl and Cs. It has long been known, that the presence of the impurities on metal surfaces can both shift position and change the widths of the electronic levels. It is shown that for an accurate description of the system it is important to use support basis functions centered on the impurity. We also investigate the accuracy of a classical treatment of electron transfer in atom metal collisions and compare it to Monte Carlo based quantum mechanical calculations. It is shown that for slow particles the treatments deviate from each other, thus giving different predictions for the sticking effects on the surface.86 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
