Among ionising radiation, alpha and beta particles are charged particles that have widely attracted research attention because of their use in a number of applications including smoke detectors, ...

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 ...

After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma ...
