Progress towards laser spectroscopy of atomic and molecular positronium

D. B. Cassidy; T. H. Hisakado; V. E. Meligne; H. W. K. Tom; A. P. Mills

The production of molecular positronium and the existence of excited states of this molecule make it natural to consider performing laser spectroscopy on this four-particle matter-antimatter system. We report here progress towards this goal, including the production of a more intense positron beam and the development and testing of laser systems suitable for spectroscopy of atomic and molecular positronium.
