The double beta processes in Mo are investigated both theoretically and experimentally. An extension of the quasiparticle random-phase approximation (QRPA) approach has been used for the two-neutrino double beta calculations. A HPGe detector and an external source of high-purity natural molybdenum are used to determine new stringent limits on the (0ν+2ν)β+ EC decay to the ground state and on (0v+2v) ECEC transitions to excited states. © 1995 American Institute of Physics.
