The presence of sinks-traps at the nodes of a 1D chain disturbs coherency of propagation of a quantum particle in the chain. This results in nontrivial dependences of the quantum yield of capture on the trap intensity and initial placement of the particle. We obtain these dependences in the cases of infinite, semiinfinite, and finite chains with one or two traps. (C) 2017 Elsevier B.V. All rights reserved.
