Resumen:
We report CDW-EIS theoretical calculations of mean recoil-ion and electron longitudinal momentum in He single ionization by proton and antiproton impact as a function of the impact energy from 50 keV to 1 MeV. At intermediate energies the mean momenta of both electron and recoil ion are significatively different for proton and antiproton impact. At larger energies mean values for proton and antiproton cases approach one another as the Born approximation turns out to be valid.
