Abstract
Measurements of the exponential attenuation of electron currents in a straight line collision chamber are reported using methane gas as the scattering medium. From the transmission spectra obtained at different methane pressure in the scattering chamber, the total cross sections for the energy range 0–16 eV are derived and compared to previous measurements. A small structure in the region of the Ramsauer–Townsend minimum is observed, confirming earlier interpretations of electron swarm experiments. A possible mechanism of excitation is discussed.Keywords
