Abstract:

This report summarizes recent progress in an experimental investigation of reactive and inelastic scattering of fast metastable rare gas atoms by various target molecules. Detailed investigations have been made of reactons between He 2 to the first power s, He2 to the 3rd power s, and Ar projectiles and O2 target molecules. Collisional ion-pair formation differential cross sections and electronically and vibrationally inelastic cross sections have been emphasized. Classical trajectory calculations on diabatic potential surfaces have been used to model and interpret the experimental results. Author
