Abstract

s-wave scattering of positrons on atomic hydrogen is treated by solving the Faddeev equations. Elastic phase shifts below the Ps(n-1) excitation threshold and the K-matrix elements within the ore gap between the Ps(n=1) and H(n=2) thresholds are calculated as well as the zero-energy 2γ annihilation rate of the

e^{+}

e^{-}

pair.
