Triple differential cross sections for the ionization of tetrahydrofuran by electron impact

We provide triple differential cross sections (TDCS) for the ionization of tetrahydrofuran (THF) by single electron impact in coplanar asymmetric kinematics in the intermediate energy regime. For the C-s and C-2 THF isomers, the analysis is carried out using (i) the highest occupied molecular orbitals energies available from ab initio calculations, and (ii) the TDCSs computed from a Coulomb wave (CW) and a distorted wave (DW) to describe the ejected electron. The calculated TDCSs using both the CW and DW models are in better agreement with experimental data than those obtained using the molecular three-body distorted wave model. Hence, we show that the developed framework can be applied to a relatively complex molecule and that the proposed models successfully describe the ionization of both THF isomers.
