In contrast to conventional charge-transfer theory, the scattering of state-selected on Pt(111) shows a dramatic enhancement in the yield of at an impact energy of 26 eV. Coincident with this resonance, the product scatters with additional translational energy. The observed scattering behavior is consistent with a collision-induced deformation of the lattice that evolves in phase with the departing projectile. The experimental data demonstrate the strong coupling between the motion of the platinum lattice and the surface electronic states responsible for charge transfer.
