摘要：

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. © 1995 The American Physical Society.
