Abstract
Differential cross sections for collisions of Na and SF6 from beam exp eriments are presented. The SF6 is vibrationally excited to the 5 nu(3 ) level with a CO2 laser. Enhancement of reactive scattering is detect ed for different energies (0.25 eV, 1.04 eV and 2.70 eV) and at labora tory angles between 10 and 75 deg. The amount of elastically scattered Na from excited SF6 always decreases in comparison with ground state scattering. The experiments show that the reaction is more efficient i f vibrational energy is put into SF6 as compared with exciting Na elec tronically.
