In the original article, the calculation methods were given in the first part of the section 4.Calculations. The rest of that section was devoted to the result of the calculations.
The figure with the general shape of the deflection function (and related expressions) has been copied from the mesoscopic module MESO-m3c-defl. Such a copy can be implemented via a hyperlink that puts the existing figure on the screen, for example in a separate window, instead of being `hard wired' as a new copy into the text of the new module.
We have tried to split the description and discussion of the complete set of theoretical tools for the calculation of the cross section into separate constituent modules, because of the size and complexity of the module: the model with the general expression would then be separated from the different approximations used to calculate actual results using the model.
However, these parts are too closely entangled, because all components refer to the expression for the semiclassical cross section and to the branches of the deflection function, both approximations use the JWKB approximation for the phase shift, and the theoretical results are calculated using both approximations (for different angles, but in the same figure).
A full account of the approximations could still warrant separate modules, but they are applied to the specific case of NaI presupposing that the reader knows about the general idea - which is explicit in links to that general info. For full accounts of the JWKB phase shift, stationary phase, and uniform approximation, we refer the reader elsewhere. In this appendix, we have not provided any higher-level modules providing that information.
The essay path now leads to A08-m5a, the Qualitative interpretation; the experimental results have already been visited and the theoretical results are visited in the Interpretation module where they are generated, not in the module Treated results, which only contains copies of the theoretical results.
