摘　　要：We investigate high partial wave resonances in positron-hydrogen scattering using the momentum-space coupledchannels optical method above the H (n =2) threshold.Resonances with angular momenta of L =0-6 are reported.Ionization continuum and positronium formation channels are included via a complex equivalent local potential.Comparisons with the existing theoretical results are presented.
