Quantitative interpretation: differential cross section = A08-m5bii

For a quantitative explanation of the measured differential cross sections for the chemi-ionization process in collisions between Na and I [experimental results given in Treated results (link type: 'DEPENDS ON'; to: A08-m4bi)], we calculate the theoretical cross sections using a semi-classical atom-atom model for ion-pair formation in molecular collisions [model given in Theoretical methods (link type: 'DEPENDS ON'; to: A08-m3c)].

In the first specific calculation of the differential cross section, we only take into account the Landau-Zener coupling between the potential curves of the system when we determine the theoretical differential cross section. Comparison between the experimental and the theoretical curves shows some persisting discrepancies [interpretation of cross sections with LZ given in Quantitative interpretation (link type: 'CONTAINS/seggregated in /specialised in/is detailed in/focused in'; to: A08-m5bii1)]. Therefore we take into account rotational coupling as well, which explains the discrepancies interpretation of cross sections with LZ and rotation given in Quantitative interpretation (link type: 'CONTAINS/seggregated in/specialised in/is detailed in/focused in'; to: A08-m5bii2)].
