ABSTRACTTotal Electron Scattering Cross Sections of CH4, NH3, PH3 and SiH4 Molecules for Intermediate Energy ElectronsT. Wijeratne Total electron scattering cross sections of CH4, NH3, PH3 and SiH4 molecules have been obtained for intermediate energy electrons by measuring the attenuation of the electron beam through a gas cell. Present cross sections are in good agreement with those produced by other experimental groups using the same experimental technique for the entire energy range in this study. However the cross sections produced by a modified Ramsauer technique are in agreement with the present measurements only up to about 1200 eV. At energies higher than 1200 eV those cross sections are systematically lower than present measurements. The differences in the cross sections produced by two experimental methods may have resulted from the poor angular resolution of the Ramsauer technique.
