The differential cross section for chemi-ionization in
K + Br2
K+ + Br2-
collisions
is interpreted qualitatively in this module with a simple classical atom-atom model for ion-pair formation in molecular collisions, with the impact parameter approximation
,
via the general shape of the deflection function.
Most of the general shape of the experimental
K + BR2
cross-section curve can indeed be explained using the classical model
.
For small angles a quantum mechanical explanation is suggested
