Аннотация:Brownian particle survival is studied in the case where traps are gathered in clusters. If the number of traps n in a cluster is small, the trap clustering is only manifested at the final stage of the process. In the opposite limit, the clusters are perfectly absorbing and trapping proceeds considerably slower than that by noncorrelated traps from the very beginning. We treat the intermediate case, where n is neither small nor large, and present an approximate expression for the rate constant that connects the two limiting cases. The results are in agreement with computer simulations.
