Positron scattering from 3-hydroxy-tetrahydrofuran

We report on the first measurements of total cross sections for positron scattering from the important bio-molecule 3-hydroxy-tetrahydrofuran. In this case the energy range of our work is 0.4–18.4 eV. While there are currently no theoretical data against which we can compare these results, a comparison with corresponding measurements for the geometrically similar species tetrahydrofuran is made. This comparison enables us to infer information on the role that the conformers of 3-hydroxy-tetrahydrofuran play in the scattering process.
