We report experimental energy distributions and yields of electrons emitted from MgO surfaces under the impact of slow noble gas and sodium singly charged ions at varying incident energies. At impact energies below $1 keV, electron spectra are nearly independent of ion type and energy. A tail of hi
Electron stimulated desorption from the MgO(100) surface has been studied over the energy range up to 500 eV. The observed threshold of the ESD Q desorbed ion from the MgOf 100) clean surface at 55 eV incident electron energy agrees well with the excitation energy of the Mg 2p core level. The kineti
