摘要：
We present in this communication the results of our calculation of TDCS and FDCS of (e,2e) and (e,3e) processes respectively on the He-like ions at incident electron energy of 1099 eV. We have performed the calculation using distorted wave Born approximation (DWBA) formalism for (e,2e) process and three Coulomb (3C) wave approach for (e,3e) process in shake-off mechanism. We present the angular profiles of TDCS in coplanar asymmetric geometry as well as that of FDCS in constant theta(12) mode and discuss the role of atomic number Z on it. We also discuss the similarities and dissimilarities between (e,2e) and (e,3e) processes of He-like ions.
