Abstract
The self-consistent-field method is used to calculate optimised s and p pseudo-states for the low-energy (00<or=1) elastic scattering and annihilation of positrons by hydrogen atoms. The elastic s-wave phaseshifts and the annihilation rates are determined at functions of incident energy and are compared to similar close-coupling and algebraic pseudo-state calculations where available. In addition, the angular correlation of two-photon pair annihilation radiation at zero energy is presented for the various models considered.Keywords
