Coupled-Channel Investigation of Collisions of Protons and Antiprotons with Hydrogen Atoms in the 2p States

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