Impact-parameter dependence of K-vacancy production in Cuq+-Kr collisions

Abstract
The authors have measured the impact-parameter (b) dependence of the probability (P) for production of K vacancies by 55 MeV Cuq+ ions on a Kr target. The absolute probability scale is found to increase in proportion to the number of L vacancies brought in by the projectile, but the shape of P(b) is nearly independent of projectile charge state. This shape is not in good agreement with that expected for the 2p pi -2p sigma rotational-coupling mechanism.
