- Аннотация: A new approach to describing the kinetics of diffusion-controlled processes of the A + B --> B type is suggested. It is applied to scrutinize two sorts of effects ignored in the traditional theory, namely, mutual effect of species B (traps) on the decay kinetics of species A (many-body effects) and the influence on it of the correlations between trap positions (correlation effects). Inclusion of the many-body effects has shown that the rate of the process is always slower than that predicted by the traditional theory. This deceleration is accounted for at the initial stage of the process by derived corrections to the rate constant and at long times, by the well-known fluctuation asymptotics. Inclusion of the correlation effects reduces to replacement of the actual trap concentration by an effective concentration calculated from the equation of state of the trap ensemble. Destruction of species in traps, with attraction (repulsion) dominating in the interaction between them, is shown to occur slower (faster) than destruction in non-interacting traps. In the one-dimensional case an exact solution to the problem is found.
