Two discrete ordinates methods, the Sn and streaming ray methods, are applied to electron transport problems. Calculational results in the form of energy deposition profiles are compared with those obtained by the method of moments for the case of a 200-keV plane perpendicular source embedded in infinite aluminum. In a second set of calculations, Sn and streaming ray flux data are compared with results of a recently developed analytical benchmark technique applied to the solution of the energy-independent form of the Spencer-Lewis equation for electron transport. Satisfactory agreement with moments and analytical benchmark calculations is found. Areas of divergence among the various calculational methods are examined.
