Observation of a shape resonance of the positronium negative ion
When an electron binds to its anti-matter counterpart, the positron, it forms the exotic atom positronium (Ps). Ps can further bind to another electron to form the positronium negative ion, Ps(−) (e(−)e(+)e(−)). Since its constituents are solely point-like particles with the same mass, this system p...
