The five-state R-matrix calculations of Berrington et al. (1975) on the excitation of helium by electrons have been revised and extended to higher electron impact energies. Inelastic scattering cross sections are presented for all transitions between the 1<sup>1</sup>S, 2<sup>3</sup>S, 2<sup>1</sup>S, 2<sup>3</sup>P and 2<sup>1</sup>P states of helium, and elastic cross sections are presented for the n=2 states.
