Certain isotopes such as Indium-115 (In-115) are extremely long lived, taking over 100 trillion years for half of the Indium atoms to decay away. These isotopes allow scientists to probe the precise internal processes that govern other extremely long-lived isotopes. New research helps scientists improve the frameworks they use to calculate half-lives and other nuclear properties, such as the structure of the protons/neutrons inside the nucleus.
