Interrelation between charge exchange and energy loss of particles interacting with surfaces

In the interaction of particles approaching a surface energy dissipation to the surface and charge exchange processes between the incoming ion or atom and the surface are two features which have found continuous interest over decades. Only few workers tried to resolve the interrelation of the change of the charge state of the incoming particle and the energy lost during the interaction. In this paper a brief review of earlier work in this field is given and some recently obtained new experimental and theoretical results are presented concerning the interaction of slow (2--5 keV) incoming He ions with a Ni(110) surface
