Abstract
The energy loss for Ne atoms scattered with keV energies from a LiF(001) su rface under channeling conditions, i.e., glancing angles of incidence, is s tudied via computer simulations using classical trajectories. Our simulatio ns show that the elastic energy transfer to the crystal lattice depends sen sitively on lattice vibrations at the crystal surface, From comparison with recent experimental data we derive surface Debye temperatures of 215(-50)( +100) K for the LiF(001) surface.
