LECTRON EMISSION FROM MULTIELECTRONIC ATOMS BY ION IMPACT D.M. McSherry, S.F.C. O'Rourke and D.S.F. Crothers Department of Applied Mathematics $\&$ Theoretical Physics The Queen's University of Belfast, Belfast BT7 1NN, N.Ireland A code has been developed to produce results for the single ionization of multielectron atoms using the continuum-distorted-wave eikonal-initial-state (CDW-EIS) and the continuum-distorted-wave (CDW) models. This is able to produce results for atoms ranging from hydrogen up to and including neon.
