We study alkali atom-halogen molecule charge-transfer collisions. , . We measure in eV molecular beam experiments the relative differential cross sections for chemi-ionisation of the systems K + Br₂ at initial relative kinetic energies of 10.35 and 6.9 eV, K + I at 11.15 eV and Li + Br₂ at 6.25 eV.

Then we try to explain the measurements on the process K + Br₂ -> K⁺ + (Br ... Br^-) with simple classical atom-atom model, using the impact-parameter approximation, an isotropic intermolecular potential and neglecting the internal states of the X₂ molecule , both qualitatively and quantitatively by comparing them to calculations based on the model .
