We present a search for b+/EC double beta decay of 120Te performed with the CUORICINO experiment, an array of TeO2 cryogenic bolometers. After collecting 0.0573 kg×y of 120Te, we see no evidence of a signal and therefore set the following limits on the half-life: T½ > 1.9×10^21 y at 90% C.L. for the 0n mode and T½ > 7.6×10^19 y at 90% C.L. for the 2n mode. These results improve the existing limits by almost three orders of magnitude (four in the case of 0n mode).

Abstract

We present a search for b+/EC double beta decay of 120Te performed with the CUORICINO experiment, an array of TeO2 cryogenic bolometers. After collecting 0.0573 kg×y of 120Te, we see no evidence of a signal and therefore set the following limits on the half-life: T½ > 1.9×10^21 y at 90% C.L. for the 0n mode and T½ > 7.6×10^19 y at 90% C.L. for the 2n mode. These results improve the existing limits by almost three orders of magnitude (four in the case of 0n mode).
