The impact parameter method is used to calculate the inelastic scattering cross sections of protons and antipro-tons, which raise hydrogen atoms from the 2p states to the n = 3 states. The calculation involves the n = 1, 2, 3states of the target and covers the energy range from 3kev to 2500keV. The study of the influence of the signof the projectile charge is the main target of this investigation. Therefore, the exchange effects in the case ofproton-induced reactions are ignored. The results of the calculations are in reasonable agreement with a previouswork.
