Time Behaviour for Diffusion in the Presence of Static Imperfect Traps

We analyze a d~ffusi~n-c~n~r~~i~s ystem of particles undergoing a trapping reaction at static sites. We show different time behaviors arising from diferent distributions of traps. Analytical and simulated resutts of the mean distance from a trap to the nearests non-absorbed particle, and of the mean number of particles between traps, are shown
