Theoretical calculations predict a complex excited state (0+) for helium-4 (4He) at the 20.21 MeV energy level. This state involves a coupling of three cluster configurations: hydrogen-3 and a proton, ...

A team of fusion researchers demonstrated that ions with energy in mega electron volt range are superiorly confined in a plasma for the first time in helical systems. This promises alpha particle ...

Two teams of nuclear physicists have carried out the most sensitive measurements yet of how an excited form of carbon-12 known as the Hoyle state breaks down into its three constituent alpha particles ...

Alpha recoil: Conceptual drawing of the experiment, which detects the nuclear decay of individual helium nuclei by embedding radioactive atoms in a micron-sized object and measuring the object’s ...
