Popis: We revisit the question as to how cross sections for direct reactions, caused by a projectile of positive charge interacting with an atom at asymptotic velocities, heal to the first Born approximation. Finite Hilbert basis calculations indicate that for protons the cross section approaches the Born result from above. We can confirm this result for shorter range Yukawa potentials by using Response Theory but not for the Coulombic problem of direct interest.
