Positronic Atoms - A Search for Positron Bound States. An experimental verification of positron bound states will solve a long standing problem in positron physics. A clear understanding of positron binding and the underlying mechanisms will open a new era in low-energy positron-atom/molecular physics, leading the way for breakthrough sciences. For instance, a positron bound state should enhance the annihilation rate between the positron and target valence electron.

A clear understanding of positron binding and the underlying mechanisms will open a new era in low-energy positron-atom/molecular physics, leading the way for breakthrough sciences. For instance, a positron bound state should enhance the annihilation rate between the positron and target valence electron. Positron annihilation, to produce two gamma rays, is a key process in both materials research (e.g. as already heavily employed in defect detection) and bio-medical treatments (e.g. the Positron Emission Tomography, or PET).Read moreRead less
