## Solution of coupled integral equations for quantum scattering in the presence of complex potentials.(English)Zbl 1305.81130

Summary: In this paper, we present a method to compute solutions of coupled integral equations for quantum scattering problems in the presence of a complex potential. We show how the elastic and absorption cross sections can be obtained from the numerical solution of these equations in the asymptotic region at large radial distances.{
