Calculations of scattering of N₂ molecules from Ru(0001)

The state resolved inelastic scattering by the Odense group of N₂ interactions with Ru (0001) surface was investigated. The scattering data was compared with theoretical model for explaining the surface collisions in systems involving small molecular projectiles using mixed classical-quantum treatment of surface scattering, to calculate average final translational energy normal to the surface as a function of final rotational energy. On the comparison of value of average final translational energy and final rotational energy with two set of conditions, one using the Ru as the surface mass and the other with an effectives surface mass 2.3 times that of single RU atom, it was observed that negative correlation existed between average final translational energy and final rotational energy . Result shows that energy transfer for incident energies is greater than 0.4meV due to higher translational energy of particles in directions and less energy transfer in large surface mass.
