Abstract : The normalized results of relative measurements of electron production cross sections differential in angle over the 30 to 150C range and in ejected energy over the 4 to 200 eV range are tabulated. Primary electron energies from 50 to 2000 eV were used in the study of He, N2, and O2. The remaining gases (Ne, Ar, Kr, Xe, H2, CH4, NH3, H2O, N2, C2H2, CO, NO, O2, and CO2) were studied under 500 eV impact. Measurements were performed in a crossed-beam apparatus with the use of a rotatable electron gun and a fixed hemispherical electrostatic energy analyzer. (Author)
