Physics

After an introduction on the various experimental techniques to be adopted in searches for double beta decay, the new approach based on the use of cryogenic low temperature detectors is described. The present results are reported on the limit for neutrinoless double beta decay of n¹³⁰Te obtained with the large bolometric detector CUORICINO. This setup consists of 44 cubic crystals of natural TeOn₂ with 5 cm sides and 18 crystals of 3 × 3 × 6 cmn³. Four of these latter crystals are made with isotopically enriched materials: two in n¹²⁸Te and two …
