Popis:	We report results for e±–Ps(1s) scattering in the energy range up to 80 eV calculated in 9-state and 30-state coupled pseudostate approximations. Cross-sections are presented for elastic scattering, ortho–para conversion, discrete excitation, ionization and total scattering. Resonances associated with the Ps(n=2) threshold are also examined and their positions and widths determined. Very good agreement is obtained with the variational calculations of Ward et al. [J. Phys. B 20 (1987) 127] below 5.1 eV.
