Semiclassical treatment of atom–surface scattering: He–Cu 001/ collisions

We formulate from a semiclassical treatment of atom–molecule dynamics an analytical expression for the time-of-flight energy loss spectra. The expression is used on He–Cu 001.scattering. The results are discussed in the context of alternative theoretical models and experimental data. q1999 Elsevier Science B.V. All rights reserved.
