Scattering and Annihilation Experiments Using a Trap-Based Beam

Sullivan, James; Barnes, L D; Marler, Joan P; Gilbert, Stephen J; Surko, Clifford M

Description

The buffer gas trap technique for positron trapping and beam formation has made available a low energy, high resolution positron beam for the first time. This has opened the way for a range of new studies in positron-atom(molecule) scattering, including measurements of annihilation cross sections (Zeff) as a function of energy and processes such as excitation by low energy positron impact. New light is now being shed on the interactions of positrons with ordinary matter, including the first...[Show more]
