Inelastic neutron scattering spectroscopy of hydrogen adsorbed on Raney nickel

Abstract
We have obtained new results by inelastic neutron scattering spectroscopy for the adsorption of hydrogen on Raney nickel. Our interpretation is based on the vibrational frequencies and on the peak intensities which have been simulated for the different samples. We conclude that hydrogen is preferentially adsorbed in sites of C3v symmetry but that a significant occupation of sites having nearly three-fold symmetry can also be found for some samples.
