  • The electronic excitation of atoms in atomization processes studied by resonance ionization mass spectrometry
  • Published at:AIP Conf. Proc. -- April 1, 1995 -- Volume 329, pp. 91-94
  • A laser ionization spectrometer designed for studying the atomization of metallic surfaces is presented. First experiments on polycrystalline nickel bombarded by 15 keV Ar+ ions are reported. The sputtered neutral atoms are selectively excited and ionized using resonance ionization spectroscopy. A comparison is made between the two step-one colour and the two step-two colour schemes. The influence of autoionizing states on the ionization process is discussed.
