Triple differential cross section for THF electron-impact ionization

POSTER

Abstract

We report a combined experimental and theoretical study of triple differential cross sections for intermediate-energy 250 eV electron-impact ionization of THF (C4H8O), for the highest occupied molecular orbitals (HOMO)[1-2]. The theoretical cross sections were calculated within a molecular 3-body distorted wave (M3DW) framework employing a proper orientation average and the results are compared with experiment for three different planes for the ejected electron, and in each plane, two different scattering angles of 6⁰ and 10⁰ and three different ejected electron energies of 10, 15, and 20 eV. We fully assess the ability of the theoretical model to reproduce the experimental data in terms of angular distribution and intensity.
