Investigations of positronium formation and destruction using PsARS

  • 1. Department of Physics and Astronomy, Wayne State University, Detroit, MI 48202 (United States)

Description

A new method of spectroscopy PsARS (positronium annihilation ratio spectroscopy) has been developed where ratios are determined of detected coincidence signals resulting from the three γ-ray decay of ortho-Ps to coincidence signals from the two γ decay of para-Ps and conversion of ortho-Ps into two 511 keV γ-rays. Some of the initial results obtained from using PsARS to investigate the formation of positronium in gases and the destruction of ortho-Ps at a surface are presented
