Small-angle specular reflection of 10-30 keV Ar+ ions from (001) and (011)Cu faces has been experimentally studied. The half-widths of reflected ion spatial distributions have been found to decrease nonmonotonically as the primary ion glancing angle decreases. For the (001) Cu face in the studied range of glancing angles (3-16°) a local decrease of spatial distribution half-width has been observed in two narrow transient regions. Angular positions of these regions have been found to correspond to some fixed values of transverse energy. A "large"-angle transient region is associated with the glancing angle at which favourable conditions for ion-focusing in surface semichanncls take place. The relationship of low-angle peculiarities in spatial distributions, energy spectra and azimuthal dependences of the reflected ion intensity to near-surface channeling is discussed. |
