Alpha decay represents a fundamental mode of radioactive disintegration wherein an unstable nucleus emits an alpha particle—a tightly bound cluster of two protons and two neutrons. This process not ...

Researchers have observed a rare nuclear decay. Namely, the team measured low-kinetic-energy protons emitted after the beta decay of a neutron-rich nucleus beryllium-11. Researchers from the National ...

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 ...
