Abstract
The angular distributions and energy spectra of positive and negative ions reflected from a vanadium alloy (V-4Cr-4Ti) bombarded by beams of low energy (1-2 keV) ions of H, He, and O were measured. The intensities of H+ or H- produced from reflection of 2 keV H+ beam at the surface of vanadium alloy showed the maxima at the angles closer to the surface normal from the mirror reflection angle, compared with Mo and W samples. The time dependence of the angular distributions of the reflected H+ or H- ions measured at the sample temperature of about 240-260 °C showed a shift of the peak in the angular distribution to the mirror reflection angle.
