An electron source is described that provides, by means of an electrostatic velocity analyzer, for velocity selection on an electron beam before scattering. The energy width of the electron beam is sufficiently reduced to resolve the transitions to the 5/sup 1/P and 6/sup 1/P states in helium. These states are separated by 0.17 v. Relative oscillator strengths for two additional members of the Rydberg series 1/sup 1/S yields m/sup 1/P were determined by study of the zero angle electron scattering. (auth)
