Three-potential formalism for the three-body scattering problem with attractive Coulomb interactions - art. no. 062721

A three-body scattering process in the presence of Coulomb interaction can be decomposed formally into two-body single channel scattering, two-body mu ltichannel scattering, and genuine three-body scattering. The corresponding integral equations are coupled Lippmann-Schwinger and Faddeev-Merkuriev in tegral equations. We solve these by applying the Coulomb-Sturmian separable expansion method. We present elastic scattering and reaction cross section s of the e(+) +H system both below and above the H(n = 2) threshold. We fin d excellent agreements with previous calculations in most cases.
