摘要：
We report new coplanar measurements of the (e,2e) TDCS for the ionisation of helium Is-shell and argon 3p- and 2p-shells. The kinematics employed remained rather unexplored to date, and could be investigated here using an improved version of our multi-angle (e,2e) spectrometer, with increased sensitivity. The results are discussed in the light of state-of-the-art theoretical models. (c) 2007 Elsevier B.V. All rights reserved.
