Abstract
Laser resonance-ionization spectroscopy of nitric oxide (NO) molecules desorbed by electron impact from a polycrystalline nickel surface is discussed. This is the first time that ground-state rotational and vibrational populations have been probed for neutrals in electron-stimulated desorption. The results support previous studies that indicate that shallow valence-level excitations dominate the neutral desorption mechanism.Keywords
