N2 - A high-resolution (ΔE ∼ 60 meV FWHM) positron beam apparatus is briefly described and it has been used to measure total scattering, elastic scattering, positronium (Ps) formation, and inelastic scattering cross sections from a number of rare gas atoms. In this paper we present a selection of these results for helium, neon and argon and where possible, compare with previous measurements and contemporary theory. A particular search has been made for resonance and channel coupling effects at, or near, the opening of inelastic channels.
