Elastic electron-hydrogen scattering phase shifts for L=1 are calculated from the Kohn variational principle, using up to 84 "Hylleraas-type" trial functions. Accuracy of the resulting phases varies from one to four significant figures, depending on the energy. A resonance appears in the 3P waves at 9.727 eV. Elastic P-wave positron-hydrogen phase shifts are also calculated.
