Abstract
A three-state and a six-state close-coupling approximation have been employed to investigate the e−-Ps scattering below the first excitation threshold of the Ps atom. Present s- and p-wave phase shifts and total cross-sections are compared with the corresponding predictions of Ward et al. (J. Phys. B, 20 (1987) 127). All the Feshbach resonances below the n = 2 threshold, including 3Se and 3Pe resonances as predicted by Ho (Phys. Lett. A, 120 (1984) 348 and Phys. Rev. A, 60 (1999) 2834), have been obtained.
