B. Chopard et al., PROPERTIES OF THE REACTION FRONT IN A REVERSIBLE A-HALF-ARROW-RIGHT-OVER-HALF-ARROW-LEFT-C(G)(K) REACTION-DIFFUSION PROCESS(B), Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 47(1), 1993, pp. 40-43
We study the properties of the reaction front formed in a reversible r
eaction-diffusion process, [GRAPHICS] with initially separated reagent
s. It is shown that the dynamics of the front can be described in term
s of a crossover between ''irreversible'' scaling at short times (t <<
g-1) and ''reversible'' scaling at long times (t >> g-1). The reversi
ble regime is dominated by diffusion and the critical exponents charac
terizing the properties of the front are independent of dimension.
