Neutron-Scattering Study of Ethylene Motions on Graphite Surfaces

Abstract
Quasielastic and inelastic, incoherent scattering of neutrons has been used to probe the diffusional and vibrational motions of ethylene molecules on graphite basal-plane surfaces. The experimentally observed dynamical response is found to agree reasonably well with molecular-dynamics simulations of ethylene films under similar conditions of coverage and temperature.
