| Abstract: | Collisions ot fast metastable beams of Ar, H, and D atoms, and H2 and D2 molecules with NO2 producing positive ions and NO?2 were studied. The ratio of the 3B1-1A1 NO?2 cross sections is a linear function of the projectile velocity. This finding is tentatively interpreted in the framework of a Landau-Zener model Earlier results on O?2 are re-examined. |
