When the number of protons changes, an atom of a different chemical element is created. By contrast, there are radioactive decay processes that do not result in a nuclear transmutation. The energy of ...

Radioactive decay is a spontaneous and random process. A block of radioactive material will contain many trillions of nuclei and not all nuclei are likely to decay at the same time so it is ...

ENSDF is a database that contains evaluated nuclear structure and decay information for over 3,000 nuclides. An international network of evaluators regularly contributes to the database, which is ...
