Recovery temperature for nonclassical energy transfer in atom-surface scattering

Abstract

Nonperturbative expressions are derived for the angular resolved energy transfer spectra in the quantum regime of multiphonon scattering of inert gas atoms from surfaces. Application to He atom scattering from a prototype heatbath Xe/Cu(111) shows good agreement with experiments. This enables a full quantum calculation of the total energy transfer $\mu$ and therefrom the much debated recovery or equilibrium temperature $T_r$ characteristic of zero energy transfer in gas-surface collisions in the free molecular flow regime. Classical universal character of $\mu$ and $T_r$ is refuted.
