Abstract : The collision of atoms with crystalline surfaces has an analogue in the semi-infinite linear chain of harmonically coupled particles struck on one end by an incident particle. Using this simple model, four different effects have been evaluated and compared with experiment: (1) the variation of the condensation efficiency with the mass of the impinging particle and with the strength of binding to the lattice; (2) the deexcitation of these atoms immediately after capture; (3) the efficiency of energy transfer to the lattice (accommodation coefficient) for collisions in which capture does not occur; and (4) the influence of defects on these quantities.
