Kinetic Reaction Coefficients in Rocket Exhaust Plumes.

Abstract

This report describes progress in the experimental program to measure reaction rates for the following reactions: (1) HCl + e yields H + Cl- (2) K + Cl yields K(+)+ Cl- (3) K(+)+ e + M yields K + M. Measurement of the rate for (1) has been complicated by the large rates for clustering reactions (4) Cl(-)+ HCl + M yields (Cl.HCl)(-)+M. The equivalent attachment coefficient for the first cluster formation (n superscript n = 1) is given as a function of E/p. Performance of a crossed molecular beam apparatus for measurement of the energy dependence of collisionial ionization of potassium and atomic chlorine (2) is described. The experimental technique to be used to measure three body recombination in potassium is described. This technique utilizes a laser induced, two step photoionization process which has been demonstrated in cesium.
