Coulomb divergence in (d,p) reactions based on Faddeev-Alt-Grassberger-Sandhas equation

The Faddeev-Alt-Grassberger-Sandhas equation is the most performance formalism to describe the (d,p) reactions since it can exactly and simultaneously treat the elastic, inelastic, transfer, and breakup reactions. In this brief report, we describe the progress and some main difficulties in treating the Coulomb interaction in the direct elastic scattering of the (d,p) reaction by using the Faddeev-Alt-Grassberger-Sandhas equation.
