Paper Abstract

A measurement program currently underway at Calspan to determine the excitation cross section (σ*) for the interaction of CO2 and H2O molecules with atomic oxygen is described. A shock-tube technique is used to drive a monoenergetic stream of atomic oxygen, in a helium plus argon diluent, into a jet of target gas injected normal to the incident beam. Subsequent radiation resulting from the collisional interaction of the highly expanded beams is observed immediately downstream using a filtered indium antimonide detector. With this experimental technique, measurements have been obtained for interaction velocities in the range of 4.5 to 7 km/sec.
