Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A ...

Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This ...

For the first time, an international research team has succeeded in observing a two-photon decay on a so-called bare atomic nucleus from which the entire electron shell has been removed. The ...

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 ...

Fig. 4: Models for the nuclear decay of abnormal pre-mRNAs that have undergone transcription termination and release from chromatin or that remain chromatin-associated. As discussed in the previous ...

Scientists have observed a brand-new and exotic atomic nucleus: aluminium-20. Unlike anything seen before, it decays through a stunning three-proton emission sequence, shedding light on nuclear ...
