LONG-TIME BEHAVIOR OF THE DIFFUSION-CONTROLLED A-]0 REACTION WITH HOPPING ENERGY RELAXATION(B)

The effect of hopping energy relaxation on the diffusion-limited react ion A + B --> 0 is considered. The main effect of the relaxation is to make the diffusion constant a decreasing function of time. We find th at fluctuation effects radically alter the decay law predicted from th e rate-equation approach, as is already known to be the case for diffu sion in thermal equilibrium. New long-time behavior is predicted for t he concentration of reacting particles as compared to the thermal equi librium case. (C) 1997 American Institute of Physics.
