It is shown that at a high impact velocity v the second-order Born term can provide a significant asymmetric (skew) contribution to the cusp at vertical-barv/sub e/ vertical-bar = vertical-bar vvertical-bar in the differential cross section for ''electron capture to the continuum'' from a hydrogenlike atom in its 1s state by a bare ion, where v/sub e/ approx. = v is the velocity of the emergent electron. The asymmetry in the cusp, heretofore unexplained, has been observed in serveral recent experiments.
