Comparing calculated linewidths of selective adsorption resonances with experimental widths measured both in specular scattering and sticking, we show that emission and absorption of single phonons and scattering via the surface corrugation determines the mean free path of H₂ and D₂ molecules trapped on a Cu(100) surface. We discuss how the mean free path depends on the physical nature of the trapped state and its relation to the sticking of the particle.
