Recently there has been much interest in the energy-transfer between a surface and an atom or molecule approaching the surface. The energy-transfer processes e.g. determine the probability that the incoming particle loses its kinetic energy and is adsorbed at the surface. In the case of metal substrates the excitation of electron-hole pairs presents a mechanism in addition to the excitation of substrate phonons. We will consider here the electron-hole (eh) pair mechanism only. As we have reviewed the theoretical description of this mechanism recently [1], we will focus here on the problems one faces in the case when the inelasticity due to eh-pairs is strong.
