“…In the theoretical treatments of Refs. [2,3], the quantum electrodynamic enhancement of spontaneous emission due to the mode modification was completely neglected, and a set of equations with phenomenologically added decay terms was used for describing the dynamics of the loading process. A more rigorous theory requires a deeper knowledge of the structure of the decay equations and the magnitudes of the decay coefficients for the translational levels of the atom.…”

We study spontaneous radiative decay of translational levels of an atom in the vicinity of a semi-infinite dielectric. We systematically derive the microscopic dynamical equations for the spontaneous decay process. We calculate analytically and numerically the radiative linewidths and the spontaneous transition rates for the translational levels. The roles of the interference between the emitted and reflected fields and of the transmission into the evanescent modes are clearly identified. Our numerical calculations for the silica-cesium interaction show that the radiative linewidths of the bound excited levels with large enough but not too large vibrational quantum numbers are moderately enhanced by the emission into the evanescent modes and those for the deep bound levels are substantially reduced by the surface-induced red shift of the transition frequency.
