Comment on the asymmetry in the cusp of the differential cross section for charge capture to the continuum

Journal Article · · Phys. Rev., A; (United States)

For electron capture from noble-gas atoms to the continuum of energetic bare projectiles an asymmetry has recently been observed in the cusp of the differential cross section at v/sub e/=v (where v/sub e/ and v are electron and projectile velocities, respectively). It is shown that the Oppenheimer-Brinkman-Kramers approximation can provide an asymmetry if terms linear in k=v/sub e/-v are kept in the expansion of the outgoing Coulomb wave. In contrast to the predictions of the second Born approximation, the resulting shape is independent of the projectile charge.
