The nature of particles yielded during electron-stimulated desorption of samarium from oxidized tungsten surface

It is established for the first time that the yield resonances related to excitation of the core electron levels of samarium (Sm) and tungsten (W) during the electron-stimulated desorption of samarium from the surface of oxidized tungsten represent neutral particles differing in the chemical nature. Most probably, the excitation of samarium levels leads to desorption of Sm atoms, while the excitation of tungsten levels causes desorption of SmO molecules.
