INTERPRETATION = A05-m5

The differential cross sections [The interpretation depends on the results (link type: 'DEPENDS ON'; target: A05-m4bi1] for chemi-ionization in M + X2 M+ + X2- collisions, in particular in K + Br2 K+ + Br2-, are explained qualitatively [To the elementary module (link type: 'CONTAINS/is detailed in/ is specified in'; target: A05-m5ai]with a simple classical atom-atom model for ion-pair formation in molecular collisions [ (link type: 'DEPENDS ON/detailed in'; target: A05-m3c] [Details in a mesoscopic module (link type: 'IS DETAILED IN/depends on/wider/range/project'; target: MESOm3c-mod] via the general shape of the deflection function. A quantum mechanical explanation is suggested for the small angles in which the classical interpretation is not valid [To the elementary module (link type: 'CONTAINS/is detailed in/ is specified in'; target: A05-m5aii].

In order to interpret the results more quantitatively [To quantitative interpretation (link type: CONTAINS/is detailed in/ is specified in; target: A05-m5b], the potential parameters and the classical deflection function of the system are determined via fitting the results calculated according to the classical model with the experimental results [To the elementary module (link type: CONTAINS/is detailed in/ is specified in; target: A05-m5bi]. Based on the potential parameters and the deflection function thus determined, the differential cross section of the collision is calculated and compared to the measurements [To the elementary module (link type: 'CONTAINS/is detailed in/ is specified in'; target: A05-m5bii] However, quantitative agreement is poor.
