Title	On the Mechanism of Low-Temperature Termolecular Atomic Recombination
BYU Creator	Pack, Russell T. Snow, Richard L. Smith, Wesley D.
Keywords	bound-complex mechanism; energy-transfer; atomic recombination kinetics;
Description/Abstract	A simple theory of gas-phase termolecular atomic recombination kinetics is presented which treats the bound-complex (BC) mechanism in a fashion which parallels the Roberts, Bernstein, and Curtiss resonance theory of the energy-transfer (ET) mechanism. The ET rate constant has a low temperature maximum, but the BC rate constant does not. The contributions of the two mechanisms to the low-temperature recombination of hydrogen atoms, with He, Ar, and H2 as third bodies, are estimated and compared. The presence (absence) of a low-temperature maximum in the observable total rate constant is determined by absence (presence) of bound vibrational levels of the hydrogen-third body van der Waals dimer. Hence, experimental studies of these reactions could yield valuable information about the interatomic potentials.
