Calculations of positron-hydrogen scattering using the close-coupling approach are reported for incident positron energies below the ionization threshold. The channel space includes nine physical hydrogen and positronium states and, in addition, eleven hydrogen and positronium pseudostates. The accuracy of our model has been validated by computations of elastic phase shifts below the positronium threshold, and elastic and positronium-formation cross sections in the Ore gap. Calculations are performed for sufficient partial waves to obtain converged elastic, positronium, and total cross sections.
