Certain isotopes such as Indium-115 (In-115) are extremely long lived, taking over 100 trillon years for half of the Indium atoms to decay away. These isotopes allow scientists to probe the precise ...

In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects interpretation of beta ...
