The results of experimental measurement of spatial-angular distributions of hydrogen particles (H-, H-0, H+) obtained in scattering of a collimated ribbon beam of H- ions and H-0(1s) atoms in He, Ar, Kr, Xe, H-2, O-2, and CO2 gas targets for certain values of energy in the range from 0.6 to 15 MeV are reported. The experimental setup and the measurement procedure with an angular resolution of 5 x 10(-6) rad are described. The angular characteristics of measured distributions, i.e., full width at half maximum and standard deviation, were determined. It is shown that the shape of distribution for a beam of hydrogen atoms produced by neutralization of H- ions in a gas target varies with the type and thickness of the target, and the angular spread is smallest for the H-2 target. The variations in the shape of distribution are due to the contribution of scattering processes without changing the charge of particles. (C) 2000 MAIK "Nauka/Interperiodica".
