The first measurements of the cross sections for neutral and charged current deep inelastic scattering in ep collisions with longitudinally polarised positron beams are presented. The total cross section for ep charged current deep inelastic scattering is presented at positive and negative values of positron beam longitudinal polarisation for an integrated luminosity of 37.0 pb H1 data and 30.5...

Model polarisation potentials for use in calculating positron-molecule cross sections are often based on approximations in which terms that depend on the sign of the charge of the projectile are neglected. Thus, these potentials do not fully distinguish between electron and positron scattering. The validity of using such potentials for positronH2 collisions is investigated by performing scatter...

The properties of hierarchical solid acid materials have been explored combining experimental catalysis findings, neutron scattering and positron lifetime spectroscopy to understand the multi-porous nature these materials.
