摘要：

We investigate the reaction kinetics for systems in which the dynamics of the particles is governed by a Langevin equation with negligible damping, and we find the expressions for the survival probability, residual concentrations, and reaction rates. We discover that the integral in time of the reaction front for d = 1 is t(1-beta)exp(-\x\/t(alpha)) for both the low and high damping limits, and we estimate the exponents a and beta in each case.
