We present a comparative study of multiple differential cross-sections in (e,3e) and (,2e) processes.We make use of initial states with different angular and radial electron–electron correlation factors in a perturbative model, and a C3 wave function to describe the final state.We also compute orthogonality factors between initial and final states. All the calculations show that a simple angular correlation can be used to achieve good qualitative as well as quantitative agreement with experimental results. © 2007 Elsevier B.V.
