Measurements of total cross sections Qi for chemi-ionization in scattering of a K2 dimer beam by a range of halogen containing molecules, at translational energies E ∼ 7-11 kcal mol-1, are reported. Substantial cross sections, Qi ∼ 2-10 Å2 are exhibited by the halogen molecules Br2, ICl, IBr, I2. Distinctly lower values Qi ∼ 0·1-0.2 Å2 are exhibited by BrCN and the mercuric and stannic halides, HgX2, SnX4. The results show a close correlation with the chemi-ionization exoergicities, particularly for formation of a K+,X- ion pair. These chemi-ionization data and results from previous reactive scattering studies are compared, in order to estimate relative reaction yields for different reaction paths. The reaction dynamics for K2 with halogen molecules and cyanohalides are rationalized in terms of the electronic structure of the potential surface, where the orientation of the K2 dimer plays a crucial role. |
