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.Keywords
