New coplanar (e,2e) experiments for the ionisation of He and Ar atoms

We report new coplanar measurements of the (e,2e) TDCS for the ionisation of helium 1s-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 sensit...

Description
Summary:We report new coplanar measurements of the (e,2e) TDCS for the ionisation of helium 1s-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.
