Electron scattering cross sections of gaseous pentanes and hexanes

Abstract

Electron scattering cross sections σv have been estimated as functions of electron velocity v for six gaseous pentanes and hexanes. The scattering cross section of each compound has a minimum in the vicinity of υ = (2–3) 107 cm/s, corresponding to an electron energy of 0.1–0.2 eV. For the pentanes, the scattering cross sections on the low energy side of the minimum increase with increasing sphericity of the molecules, while the minimum tends to shift to higher energies. The same is true of the hexanes.
