The in-plane scattering of H2 molecules at thermal energies from the (001) face of LiF was studied at low temperatures, by means of nozzle beam techniques. Both elastic and rotationally inelastic diffraction peaks were resolved over a wide range of incident and final angles. Taking into account the properties of the supersonic beam, diffraction probabilities were derived for the observed peaks. A discussion of the results in light of the present theories is given. The large probability of occurrence of rotational transitions in the presence of the surface is pointed out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
