Spin-polarised probes have been central to nuclear and particle physics since the discovery of parity violation by Chien-Shiung Wu in 1956, who detected asymmetric emission of β-radiation from low-temperature 60Co in a magnetic field. The…

Light nuclei such as the deuteron are surprisingly fragile. A deuteron is bound by only a few mega-electronvolts, yet at the Large Hadron Collider it is produced in environments that are tens of trillions of degrees – about 100,000 times hotter than…
