Deuterium scattering from Rh(110) surface

Thermal energy deuterium beam scattering (TEDS) from Rh(110) surface is reported and compared to helium atom scattering (HAS). Unlike for He, we find quite strong D2 off-specular diffraction. The D2 diffraction intensities are fairly isotropic along the [001] and [11̄0], reflecting the presence of a...

Description
Summary:Thermal energy deuterium beam scattering (TEDS) from Rh(110) surface is reported and compared to helium atom scattering (HAS). Unlike for He, we find quite strong D2 off-specular diffraction. The D2 diffraction intensities are fairly isotropic along the [001] and [11̄0], reflecting the presence of a finite dissociation barrier in the potential energy surface (PES) rather than the anisotropic corrugation of the relevant Rh(110) surface electron density. Inelastic D2 scattering with strong J=0→2 kinetic-to-rotational energy conversion is also presented and discussed.
