Temperature dependence of photon stimulated desorption of ground state and excited state Na from NaCl

A theoretical study of desorption induced by electronic transitions in alkali halides

“…Secondly, desorbed particles are energetic for desorption by core-electron excitation [16,17] but follow closely a Maxwellian for desorption by valence-electron excitation [18]. Thirdly, desorption of neutral alkali induced by valence-electron excitation exhibits a temperature dependence that is characteristic of thermal evaporation, while the temperature dependence of the desorption yield of excited alkali atoms is completely different [16,19]. Thus it is of interest to examine the consequences of valence-electron excitation and of core-electron excitation in alkali halides theoretically and to see how they are reflected in the experimental results.…”
