A simple classical atom-atom model qualitatively explains the relative differential cross sections of chemi-ionization processes M + X2 M+ + (X + X-). However, there is still no reliable quantitative explanation [link to: (detailed in/wider range/corpus) Central problem MESO-m2b] . A simple classical atom-atom model is not sufficient for the explanation of ion-pair formation in molecular collisions.}

It has already been found [Findings A04-m6a] that the total cross sections of collisions between Li or Na atoms and I atoms can be described using the Landau-Zener transition probability. The question is whether the differential cross section of such a simpler system can also be explained using the Landau-Zener model.

[click for note added in hindsight]
The differential cross section of the collision process have been determined in a later article and it was found that the cross section is indeed described by the simple atom-atom model with the Landau-Zener transition probability [Findings A08-m6a].

For a more detailed study the experimental resolution should be enhanced. Recently we have replaced the sputtering source link to: (detailed in/focussed on in/wider range/corpus) exp.meth.  MESO-m3a-sputt] by a charge-exchange source link to: (detailed in/focussed on in/wider range/corpus) exp.meth. MESO-m3a-charge] In the near future we shall determine the potential parameters of some alkali atom-halogen molecule potential curves by quantum-mechanical calculations and with the help of better resolved differential cross sections.
