Positron and electron scattering from tetrahydrofuran

We report results of total cross-section measurements for positron and electron scattering from the chemically and biologically important molecule tetrahydrofuran. We believe this is the first time such data have been reported in the literature. The positron measurements were conducted over the energy range of 0.1–20.0 eV, with the cross section being found to be strongly peaked at the lower energies. The electron energy range was 2–21 eV, with this cross section's main feature being a broad shape resonance with a peak at ∼7.5 eV.
