Making sense of the muon’s misdemeanours (IMAGE) Paul Scherrer Institute Caption By making precise measurements in an exotic atom known as muonium, Crivelli and Prokscha are aiming to understand puzzling results using muons, which may in turn reveal gaps in the laws of physics as we know them. To make the measurements, they use the most intense, continuous source of low energy muons in the world at the Paul Scherrer Institute PSI in Switzerland.
