Abstract
A detailed description of the CUORICINO Te-130 neutrinoless double-beta (0 v beta beta) decay experiment is given and recent results are reported. CUORICINO is an array of 62 tellurium oxide (TeO2) bolometers with an active mass of 40.7 kg. It is cooled to similar to 8-10 mK by a dilution refrigerator shielded from environmental radioactivity and eneergetic neutrons. It is running in the Laboratori Nazionali del Gran Sasso (LNGS) in Assergi, Italy. These data represent an exposure of 11.83 kg yr or 91 mole-years of Te-130. No evidence for 0 v beta beta-decay was observed and a limit of T-1/2(0v)(Te-130) >= 3.1 x 10(24) y (90% CL) is set. This corresponds to an upper limit on the effective mass, (m(v)), between 0.19 and 0.68 eV when analyzed with the many published nuclear structure calculations. In the context of these nuclear models, the values fall within the range corresponding to the claim of evidence of 0v beta beta-decay by H.V. Klapdor-kleingrothaus et al. The experiment continues to acquire data.
