Secondary Electron Yield γ of MgO for Ionized and Metastable Rare-Gas Molecules

摘要

The γ values of MgO without impurity levels for ionized and metastable rare-gas molecules were calculated. Resonance neutralization cannot occur with combinations of MgO and these rare gases. Therefore, the γ values of MgO for the rare-gas ionization molecules are determined by Auger neutralization only. The γ values of MgO also become zero for ionized Ar_2, Kr_2, Xe_2 molecules and the metastable Xe_2~* molecule, which has the energy of the central wavelength in the lowest continuous spectrum.
