| Abstract: | Effect of couplings of the
n = 2 states on the n = 3 excitation cross-sections in scattering of protons
and antiprotons by hydrogen atoms being initially in the 2s state has been investigated by means of the impact parameter
approximation. The calculations take into account the n = 1, 2, 3, and 4 states of the target and cover energy range from 3 -
2500 keV. The study of the influence of the electric charge of the projectile
is a target of this investigation. Therefore, the exchange effects in the case
of proton-induced reactions are ignored. The results of calculations for
protons are in reasonable agreement with a previous work. |
