In this module we aim for an exact expression of the potential and the deflection function, not yet for the differential cross section. Especially the potential may be of interest separately. The results of this module will also be used as input in A05-m5bii, where the theoretical differential cross section will be calculated.

The details of the determination of each potential parameter are available to those who need some further explanation and justification. They are hidden from first view for the clarity of the main line of reasoning.

The potential curves (including the parameters) and deflection functions that are determined here can be seen as `theoretical results'. As such, they are copied to the Treated results module A05-m4bii. They could also be provided with an extra label in some other way, that permits interested readers to locate them.

The determination of the potential parameters is almost entirely copied from the section 4.Discussion in the original article. The deflection function was already presented in the Introduction, with forward pointers to the potential given in that section 4.Discussion. However, in the Introduction only the general shape of the deflection curve was referred to. That general shape has been presented in the modular version in the mesoscopic Theoretical methods module MESO-m3a-defl.

We suppose that in Rittner's cited article details are provided on these potentials, including assumptions of terms that can be neglected, justifying and explaining the choice of this potential.

This module is the target of a "forward reference": the theoretical methods m3c refer to the value of the electron affinity of the system calculated here.
