N. Hatke et al., SURFACE CHANNELING EXPERIMENTS AT 20 MEV AND RESONANT COHERENT EXCITATION OF N6+ IONS, Physical review letters, 79(18), 1997, pp. 3395-3398
Surface channeling of 21.8 and 23 MeV N6+ ions of a Pt(110) surface is
experimentally verified. At 21.8 MeV resonant coherent excitation is
observed leading to enhanced ionization when the ions scatter along th
e [1(1) over bar0$] surface half channels.
