Electron capture in fast collisions

Abstract

Consideration is given to the problem of calculating the cross-section describing electron capture in high-energy collisions between atomic systems. The usual procedure is unsatisfactory in that the cross-section to which it leads is not uniquely determined, but instead is improperly dependent on the interaction potential adopted. A procedure which has not this defect is proposed. The impact parameter and wave treatments are both developed, account being taken in each of the effect of momentum transfer.
