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 ...

An international team of researchers has systematically measured the β-decay half-lives of 40 nuclei near calcium-54, ...

Double beta decay, one of the rarest nuclear processes, offers a unique portal into the fundamental properties of neutrinos and the conservation of lepton number. Experimental strategies have evolved ...

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 ...
