Cuoricino results for 2 decay to the first excited state 0 + Sergio Di Domizio for the Cuoricino Collaboration Università and INFN Genova Athens, June 13-19 2010
Cuoricino Cuoricino collected data at the Laboratori Nazionali del Gran Sasso between 2003 and 2008 It is an array of 5x5x5 cm 3 TeO 2 cryogenic bolometers devoted to the search of 0 decay in 130 Te Cuoricino has a mass of 42 kg (11.8 kg in 130 Te) The accumulated statistics is 19.8 kgy in 130 Te The average energy resolution is 7 keV FWHM at 2.6 MeV
130 Te 2 decay to the excited state 0 + T 1/2 > 1.4 x 10 23 y (90% C.L.) 2 de-excitation s emitted Coincidence based analysis: strong background reduction CUORICINO RESULT: More details in the poster
