Resumen:
This article considers the scattering of particles off complex, central-field potentials. Starting from the Schrödinger radial-equation, we find that the partial-wave Sl-element can be decomposed as a sum of two contributions, Sl = SlR + SlI, due to the real and imaginary parts of the potential. We obtain element SlI as the asymptotical limit (r ? ?) of a single, ordinary, first-order, nonlinear, differential equation. This equation is only associated to the imaginary part of the potential. We apply the procedure, combined with the semiclassical uniform WKB method, to the scattering of Li + HBr and K + HBr systems.
