Abstract
We report a calculation of S-wave resonances (energies and widths) in positron-hydrogen scattering below the N=2 hydrogen and the N=2 positronium excitation thresholds with the stabilization method using Hylleraastype wavefunctions. Three resonances have been extracted out of which one is associated with the hydrogen n=2 threshold and the other two are found lying below the Ps(n=2) formation threshold. The present results agree with the most accurate calculations obtained by other methods.
