Reply to the comment on 'New geometry for the quasi-binary incident electron–centre of mass collision in the (e, 3e) process on He'

Abstract

In this reply, we clarify our theoretical model used (the so-called 2CG model) in our recent paper (Choubisa and Sud 2008 J. Phys. B: At. Mol. Opt. Phys. 41 035202) and address the queries and comments raised by Dal Cappello and Ancarani. Recently, we published a paper (Choubisa and Sud 2008) in which we investigated new results in a new geometrical mode, the so-called constant θ12−φ12 mode. We claimed that we used 3C wave theory to calculate FDCS in the first as well as the second Born approximation using Le Sech and Bonham and Khol wavefunctions for the He atom. We also compared our results with other first-orderCCCtheory and experimental data and based on our comparison, we claimed that our calculation is able to reproduce mostly well-established results and hence the model is reliable enough to present our theoretical results in the proposed geometrical mode. We have also shown that we need to multiply FDCS by 3 and 0.54 factors respectively for Le Sech and Bonham and Khol wavefunctions to compare them with the absolute experimental data of Lahmam-Bennani
