Search for β/EC double beta decay of Te

We present a search for β/EC double beta decay of Te performed with the CUORICINO experiment, an array of TeO cryogenic bolometers. After collecting 0.0573 kg y of 120, we see no evidence of a signal and therefore set the following limits on the half-life: T > 1.9 *10 y at 90% C.L. for the 0ν mod...

Zusammenfassung:We present a search for β/EC double beta decay of Te performed with the CUORICINO experiment, an array of TeO cryogenic bolometers. After collecting 0.0573 kg y of 120, we see no evidence of a signal and therefore set the following limits on the half-life: T > 1.9 *10 y at 90% C.L. for the 0ν mode and T > 7.6 *10 y at 90% C.L. for the 2ν mode. These results improve the existing limits by almost three orders of magnitude (four in the case of 0ν mode).
