Treated results: Theoretical differential cross section=A08-m4bii2

Fig. A08-m4bii2-F1 a shows the polar differential cross section, defined by I() sin() , plotted against [why this plot is preferred is argued in a mesoscopic module Data treatment(link type: 'elaborated/argued in/wider range/project'; target: MESO-m3c-treat] for the chemi-ionization process of sodium on iodine and calculated by the lowest-order stationary-phase approximation. [Particulars on the calculation methods in Theoretical methods (link type: 'depends on'; target: A08-m3cii], [The calculation itself is performed in the Interpretation (link type: 'input from'; target: A08-m5] . The region of the classical rainbow angle has been omitted because the lowest-order approximation leads to a wrong result.

Fig. A08-m4bii2-F1 b shows the differential cross section with simplified interference structure. An additional simplification in Fig.  A08-m4bii2-F1 b is the separate reproduction of the attractive and repulsive scattering contribution as though they could be distinguished.

(a) Differential cross section with complete interference structure, calculated with the lowest-order stationary-phase approximation. The region of the classical rainbow angle cl,rb has been omitted.
(b) Differential cross section calculated with the stationary-phase approximation and uniform rainbow approximation showing separated the long-wavelength interference structures due to a + c (65,full curve), b + c (65250, full curve) and d + e ( 0 2300, dashed curve) interferences.
(c) Full bars indicate the measured maxima of the interference structure on the differential cross section due to net-attractive scattering. Dashed bars indicate the maxima due to net-repulsive scattering. The complete measured cross section curve at Er =13.1 eV is given in Fig. A08-m4bi1-F1.

The general shape of the differential cross section has been calculated at collision energies of 13.1, 20.7, 29.7, 38.7 and 55.0 eV, as shown in Figs. A0-m4bii2-F2a, b, c, d, e. The calculated values have been given on absolute scales. [Compare to the experimental results (link type: 'compare'; target: A08-m4bi1].

(a), (b), (c), (d), (e): Absolute differential cross sections, calculated semi-classically and also averaged over the interference structure, have been given by the dashed curves. Use has been made of H12=0.05 eV. (f): At Ei = 29.7eV the curves show the calculated differential cross section for H12=0.04, 0.05 and 0.07 eV.

(f): Effect of rotational coupling on the minimum of the differential cross section due to collisions with large collision parameters. Abscissa and ordinate scales have been extended by a factor of two with respect to the corresponding figure (e).
