Three different approaches, using coincidence techniques, are described and results presented relative to the excitation of the substrates of He (2<sup>1</sup>P) by electrons of incident energy between 30 and 80 eV and for electron scattering angles from 5 degrees to 42 degrees . One approach involved a vacuum UV polarization analysis. The results show a wide divergence between experiment and the existing theories at the larger scattering angles.
