Double beta decay to an excited state of the daughter nucleus may be considered in addition to the more probable decay to ground state. Though it suffers from a reduced phase space, the decay to an excited state has a unique experimental signature, distinguished by coincident gamma rays from the de-excitation of the daughter nucleus. So far, the two-neutrino excited state decay has only been...
