Measurement of Ion-Ion Neutralization Reaction Rates by a Merged Beams Technique.
Abstract
The forward and reverse cross sections have been calculated for Na + Cl yielding Na(+) + Cl(-) and K + Cl yielding K(+) + Cl(-) using quantum close-coupling techniques with matrix elements derived from pseudo-potential calculations. The collision energy-dependent cross sections were Boltzmann-averaged to obtain temperature-dependent thermal reaction rate coefficients. Equilibrium constants k(eq) = k(recomb)/k(ioniz) were also calculated for 1000 K < T < 3000 K. An effort was made to measure neutralization rates using and existing merged-beams apparatus. However, it proved impossible, within the limited scope of this contract, to obtain stable negative halogen beams of sufficient intensity to perform the measurement.
