Measurement of double beta decay of 100 Mo to excited states in the NEMO 3 experiment
The double beta decay of 100Mo to the 01 and 2 + 1 excited states of 100Ru is studied using the NEMO 3 data. After the analysis of 8024 h of data the half-life for the two-neutrino double beta decay of 100Mo to the excited 01 state is measured to be T (2ν) 1/2 = [5.7 +1.3 −0.9(stat)±0.8(syst)]·10 y. The signal-to-background ratio is equal to 3. Information about energy and angular distributions...
متن کاملFirst results of the search for neutrinoless double-beta decay with the NEMO 3 detector.
The NEMO 3 detector, which has been operating in the Fréjus underground laboratory since February 2003, is devoted to the search for neutrinoless double-beta decay (beta beta 0v). The half-lives of the two neutrino double-beta decay (beta beta 2v) have been measured for 100Mo and 82Se. After 389 effective days of data collection from February 2003 until September 2004 (phase I), no evidence for...

متن کاملDouble beta decay to the excited states: experimental review
A brief review on double beta decay to excited states of daughter nuclei is given. The ECEC(0ν) transitions to the excited states are discussed in association with a possible enhancement of the decay rate by several orders of magnitude.
