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 ...
For the first time, scientists observe a new and rare decay mode where oxygen-13 breaks into three helium nuclei and a proton following beta decay. Scientists have previously observed interesting ...
Left: “Mirror” nuclei lithium-8 and boron-8 undergo beta decay, then split into two alpha particles. Right: Radioactive ions from the ATLAS accelerator at Argonne National Laboratory are suspended in ...
