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
