Abstract

Astronomy & Astrophysics Physical Sciences Physics Physics, Particles & Fields Science & Technology
We present a search for beta(+)/EC double beta decay of Te-120 performed with the CUORICINO experiment, an array of TeO2 cryogenic bolometers. After collecting 0.0573 kg.y of Te-120, we see no evidence of a signal and therefore set the following limits on the half-life: T(1/2)0(v) > 1.9 . 10(21) y at 90% C.L. for the Or mode and T-1/2(2v) > 7.6 . 10(19) y at 90% C.L. for the 2v mode. These results improve the existing limits by almost three orders of magnitude (four in the case of 0v mode). (C) 2011 Elsevier B.V. All rights reserved.
