Kinetic Reaction Coefficients in Rocket Exhaust Plumes.
Abstract
During the first year of the program, the cross section photoionization of excited potassium atoms has been measured from threshold to 2500A. A drift tube apparatus with a quadrupole mass spectrometer for ion identification has been constructed to study dissociative attachment of HCl. The primary ion, C1(-), has been found to form molecular negative ions identified as HClCl(-),(HCl)2Cl(-), and the impurity ion H2O,Cl(-). For drift tube conditions near the threshold for dissociative attachment for HCl, the molecular negative ions are most abundant; at higher drift tube energies, the atomic negative ion dominates. A xenon-ion laser has been constructed and its power level optimized so that a frequency doubling crystal can be used to make a useful source of ionization for future recombination measurements. Cross sections for the formation of Cl(+) from Cl2 and HCl by electron impact have been measured from threshold to 100eV.
