Total Electron Scattering Cross Sections for Ar, N₂, H₂O and D₂O

Abstract

Total electron scattering cross sections (σ_t) for Ar, N₂, H₂O and D₂O are determined in the energy range between 7 and 500 eV using a linear electron transmission device. The thermal transpiration effect is considered. Results for Ar and N₂ are in good agreement with those of previous experiments. The present results for H₂O agree well with those of Brüche, Szmytkowski, Szmytkowski et al. and Zecca et al. However, some difference still remains among the recent results in the energy region below 15 eV. The σ_t for D₂O is much the same as for H₂O within the experimental uncertainty.
