Phys. Rev. A 65, 014702 (2001) [4 pages]Positron-hydrogen scattering at low intermediate energiesReceived 20 June 2001; published 11 December 2001 We apply the coupled-channel-optical method for positron-hydrogen atom scattering at energies just above the ionization threshold to 40 eV. The rearrangement positronium channels are treated in the close-coupling method that includes the atomic target states. The neglect of the continuum is taken into account via an ab initio optical potential model. Physical observables such as ionization, positronium formation, and total cross sections are presented together with elastic and positronium(1s) differential cross sections. © 2001 The American Physical Society URL:
