Bray, I. and Stelbovics, A.T. (1993) Convergent close-coupling calculations of low-energy positron–atomic-hydrogen scattering. Physical Review A - Atomic, Molecular, and Optical Physics, 48 (6). pp. 4787-4789.

Abstract

The convergent close-coupling approach developed by the authors is applied to positron scattering from atomic hydrogen below the first excitation threshold. In this approach the multichannel-expansion one-electron states are obtained by diagonalizing the target Hamiltonian in a large Laguerre basis. It is demonstrated that this expansion of the scattering wave function is sufficient to reproduce the very accurate low-energy variational results, provided target states with l15 are included in the expansions.
