Loss of electrons by fast H- ions in gases

The characteristic angles and cross sections for a ((1) over bar 0) + ((1) over bar 1) reaction in which H- atoms with an energy of 0.1-10 000 MeV los e electrons when scattered on C, N, or O atoms were calculated for the rela tivistic case of the Bethe scattering theory. The cross sections for N-2, O -2, and CO2 molecular targets were obtained using the additivity rule. The results presented are compared with known experimental and theoretical data .
