Abstract
Model local potentials that have been used to describe the correlation and polarization interactions in positron-molecule scattering are compared. Model density functional correlation-polarization potentials developed for electron-molecule and positron-molecule scattering are considered in addition to the distributed positron model. Results computed using these potentials are compared to available experimental data for positron-SF6 scattering. It is found that the distributed positron model gives very good agreement with experimental data in contrast to the poor agreement found with the positron-molecule correlation-polarization potential.
