(a) Inelastic electron scattering cross-section of common gas molecules (H2O, H2, N2, O2) as a function of electron kinetic energy. Data extracted from Muñoz et al. (2007) (H2O), Lawton & Phelps (1978) (O2), Phelps & Pitchford (1985) N2, and Buckman & Phelps (1985) (H2). The solid lines indicate parametrizations of the data points for Ekin > 100 eV. (b) Transmission of electrons over a distance of 0.30 mm at different pressures of the above gases. |
