Abstract

Total, integral inelastic and integral and differential elastic cross sections have been calculated with the screening-corrected additivity rule (SCAR) method based on the independent atom model (IAM) for electron scattering from tetrahydrofuran (THF). Since the permanent dipole moment of THF enhances rotational excitation particularly at low energies and for small angles, an estimate of the rotational excitation cross section was also computed by assuming the interaction with a free electric dipole as an independent, additional process. Our theoretical results compare very favourably to the existing experimental data. Finally, a self-consistent set of integral and differential interaction CSs for the incident energy range 1 eV–10 keV is established for use in our low energy particle track simulation (LEPTS). All cross section data are supplied numerically in tabulated form.
