Electron-stimulated desorption of excited atoms from solid nitrogen

The desorption of particles from the surface of solid nitrogen, stimulated by electrons having subthreshold energy, is studied in the atomic transition range using VUV fluorescent spectroscopy. Varying the energy of the electron beam allowed us to differentiate the inputs from the bulk and the sub-surface regions of the sample. Evidence of electron-stimulated desorption of excited nitrogen atoms and the mechanisms thereof are provided for the first time.
