title: Low-energy positron scattering from dihydropyran.
abstract: We report on total cross section measurements for positron scattering from dihydropyran (C(5)H(8)O), with the energy range of the present study being 0.15-48 eV. To the best of our knowledge, there are currently no other corresponding experimental data or theoretical computations against which we can compare our results. The effect of this species' important dipole moment and significant dipole polarizability on the scattering dynamics is considered, as is the opening of the positronium formation channel.
