Abstract
- The CUORICINO experiment was an array of 62 TeO2single-crystal bolometers with a total 130Te mass of 11.3kg. The experiment finished in 2008 after more than 3 yr of active operating time. Searches for both 0ν and 2ν double-β decay to the first excited 0+state in 130Xe were performed by studying different coincidence scenarios. The analysis was based on data representing a total exposure of N(130Te)•t=9.5×1025yr. No evidence for a signal was found. The resulting lower limits on the half-lives are T122ν(130Te→130Xe*)>1. 3×1023yr (90% C.L.), and T120ν(130Te→130Xe*)>9.4×1023yr (90% CL). ©2012 American Physical Society.
