Differential cross sections for ejection of secondary electrons of various energies at various angles were measured for hydrogen gas bombarded by 100-keV protons and for helium gas bombarded by 50-, l00-, and 150-keV protons. The range of angles investigated was 10° to 160° and the range of electron energies was 1 to 500 eV. A unique fixed-port, double-walled scattering chamber was used. Electrons were counted by an electron multiplier after passing through a 127° electrostatic analyzer. The efficiency of the detector was determined by replacing the analyzer and multiplier by a Faraday cup and making absolute measurements of cross sections …
