Low energy positron interactions with rare gas atoms: threshold features and benchmark cross sections

Sullivan, James; Caradonna, Peter; Jones, Adric; Machacek, Joshua; Makochekanwa, Casten; McEachran, Robert; Mueller, D. W.; Buckman, Stephen


Using a high resolution (∼60 meV FWHM) positron beam from a Surko buffer-gas trap, we have measured grand total cross sections as well as total elastic, positronium formation and electronic excitation cross sections in the rare gases. Strong threshold (
