Self-Consistent Potentials for Low-Energy Positronium Scattering

This poster presents ab initio potentials for positronium-atom and positronium-molecule interactions. Potentials are obtained by solving the Hartree-Fock equations for a range of molecular orientations and separations, using basis sets of increasing complexity. The goal of the work is to aid in the theoretical analysis of low-energy positronium collisions, such as those carried out at the positronium beam line at University College in London in recent years.
