Phys. Rev. A 63, 062721 (2001) [11 pages]Three-potential formalism for the three-body scattering problem with attractive Coulomb interactionsReceived 9 February 2001; published 16 May 2001 A three-body scattering process in the presence of Coulomb interaction can be decomposed formally into two-body single channel scattering, two-body multichannel scattering, and genuine three-body scattering. The corresponding integral equations are coupled Lippmann-Schwinger and Faddeev-Merkuriev integral equations. We solve these by applying the Coulomb-Sturmian separable expansion method. We present elastic scattering and reaction cross sections of the e++H system both below and above the H(n=2) threshold. We find excellent agreements with previous calculations in most cases. © 2001 The American Physical Society URL:
