Abstract
A LEED system which provides high resolution in energy and momentum si multaneously has been used to record electron energy loss spectra of t hin NaCl films epitaxially grown on Ge(100). While measurements in spe cular geometry show energetically equidistant dipole losses due to sin gle and multiple excitations of the surface phonon polariton, off-spec ular spectra show multiple loss features which evidently are the resul t of a combination of one impact and several dipole scattering process es with individually resolved energy and momentum.
