Electron interactions with tetrahydrofuran

Abstract

In this paper, we summarize our recent experimental and theoretical results on electron scattering from gaseous tetrahydrofuran (THF). Electron-impact ionization and total scattering cross sections were determined experimentally for energies between 50-5000 eV. Electron energy loss spectra were measured in the keV range using a transmission beam technique and for smaller energies (15-50 eV) with a crossed-beam apparatus. Using an optical potential method assuming the screening-corrected additivity rule, total, elastic and inelastic cross sections including dipole interactions were calculated (leV - lOkeV) in order to complement the experimental data. Elastic differential cross sections were also obtained. An empirical approximation to the inelastic angular distributions based on differential cross sections is proposed. The available integral and differential cross sections and energy loss distributions in the range 1 eV - 10 keV are combined into a table of recommended electron interaction cross sections with THF.
