Desorption of excited atoms and excimers induced by valence exciton excitation from the surface of solid Ne by low energy electron and photon irradiation will be presented. Excimer (Ne$_2$* $^{3}\Sigma_{u}$) desorption was experimentally confirmed for the first time, and was found to be well described in the frame work of cavity ejection mechanism as in the atomic desorption case.
