The relative differential cross section for e - -He scattering with the excitation of the 2 3 S state has been measured as a function of energy at various scattering angles. It is confirmed that the most prominent structures around 22.5 eV are due to an S, a P and a D resonance, the widths of which rise slowly from S to D.
