  We report results of differential cross sections for elastic scattering,
target-elastic Ps excitations and target-inelastic excitation of hydrogen in a
five-state coupled-channel model allowing for Ps(1s)H(2s,2p) and Ps(2s,2p)H(1s)
excitations using a recently proposed time-reversal-symmetric regularized
electron-exchange model potential. The present model yields a singlet Ps-H
S-wave resonance at 4.01 eV of width 0.15 eV and a P-wave resonance at 5.08 eV
of width 0.004 eV. We also study the effect of the inclusion of the excited Ps
and H states on the convergence of the coupled-channel scheme.
