Two-particle continuous-time random walks and binary reactions in disordered media

Abstract

The relation between unary-(trappihg) and binary (mutual annihilation) reactions in disordered systems is studied in the framework of the continuous-time random walk. It is found that if the waiting-time distribution of the walk has infinite moments, a time-independent binary rate constant may exist even though a unary one does not.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24907/1/0000334.pd
