Abstract
The plane-wave impulse approximation is used to analyse the experimental cross section for the argon (e, 2e) reaction (using the non-coplanar symmetric geometry). A series of configuration interaction calculations for the structure of Ar I and Ar II are reported demonstrating that correlation effects have only a minor effect on the momentum distributions (which are well described by the target Hartree-Fock approximation). Fair agreement between the theoretical and experimental spectroscopic factors for the separation energy spectrum is obtained, and in particular the distribution of strength amongst the 3s23p4nd2Se satellite states specified by the largest calculations is in better agreement with data than that obtained with simple structure models.Keywords
