Abstract
We study the ternary A + 2B --> C reaction-diffusion process with init ially separated reactants. A perturbation approach gives a scaling of the global reaction rate with t(1/2) at early time, followed by a cros sover to t(-1/2) in the asymptotic time regime, a behavior which is th e same as for the binary A + B-->C reaction under initial segregation. Monte Carlo simulations are in good agreement with the predicted scal ing.
