Quantitative interpretation m5b

The modularisation process
A quantitative interpretation is given in A05-m5b, by calculating the theoretical differential cross sections. This interpretation consists of two serially connected sub-problem solution processes. Firstly, the potential for the reaction between potassium and bromide is determined in A05-m5bi, which implies a long and involved determination of a series of potential parameters. This determination of the potential parameters is almost entirely copied from the section Discussion in the original article.

The expression for the potential thus obtained (which can be consulted separately as a result, because it is also included in the module Treated results) is then used as input in A05-m5bii in order to calculate the deflection function and subsequently the theoretical differential cross section, which finally can be compared with the experimental values. In the original article, the deflection function was already presented in the Introduction, with forward pointers to the potential given in the section Discussion. 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 module Theoretical methods MESO-m3c-defl.

In both cases, a numerical evaluation of the deflection function is used to calculate the differential cross section, for which the method has been described in A06. In the original article A05 this was implemented via a forward reference to an article that was ``to be published''. This untargeted forward reference is resolved in the modular version, where an explicit link has been added in module A05-m5bii.

The resulting module
In the modular version, the details of the calculation are hidden from view. Therefore, the main lines of reasoning can be followed more easily than in the original version. This satisfies the needs of readers who are only interested in these main lines, and of reader who need to an overview of the reasoning as a whole before they can understand the fully detailed account. The details can be unfolded to fulfil the requirements of readers who do not understand or accept the outcome. In principle, these details can be more elaborate than in the original version, because thus hidden they do not obstruct the main lines and in an electronic environment there do not have to be `page limits'. However, in the Interpretation modules of the examples, no additional details have been presented The mathematical elaboration does not form an information unit that can be consulted separately and therefore does not form a separate module.
