8 pags., 7 figs. -- 24th Summer School and International Symposium on the Physics of Ionized Gases ; This report will review several new experimental developments for low energy (1-50 eV) scattering of both electrons and positrons from atoms and molecules. Experiments include an apparatus for studies of scattering from unstable molecular radicals, a position- and time-sensitive time-of-flight spectrometer for studies of near threshold electronic excitation of atoms and molecules and a trap-based positron scattering experiment for measurements of low energy positron scattering from rare gas atoms. Where possible, comparisons are also made with other experimental determinations and with contemporary scattering theory. © 2008 IOP Publishing Ltd. ; It is a pleasure to acknowledge the support of the Australian Government through the Australian Research Council's Centre of Excellence program and the Department of Innovation, Industry, Science and Research's International Science Linkages Program.
