Experimental limit on the charge non-conserving β decay of 73Ge

Data collected during 637 days in the Baksan Neutrino Observatory with 1 kg high purity Ge semiconductor detector have been analyzed to search for charge non-conserving β decay of 73Ge. It is the first real-time experiment, in which one of the best up-to-date life time limits has been established fo...

Description
Summary:Data collected during 637 days in the Baksan Neutrino Observatory with 1 kg high purity Ge semiconductor detector have been analyzed to search for charge non-conserving β decay of 73Ge. It is the first real-time experiment, in which one of the best up-to-date life time limits has been established for this process as: τ CNC ( 73Ge→ 73As)>2.6×10 23 yr at 90% C.L.
