Abstract
The Milano group is using an array of four crystals of TeO2, 334 g each, to search for neutrinoless double beta decay of 130Te [A. Alessandrello et al., Phys. Lett. B 335 (1994) 519; Proc. 4th Int. Workshop on Theoretical and Phenomenological Aspects of Underground Physics — TAUP 95, to be published in Nucl. Phys. B (Proc. Suppl)]. The detectors are operating in a dilution refrigerator installed in the Underground National Laboratory of Gran Sasso specially built with low activity materials. Due to the low external background and the good energy resolution it is possible to obtain precise measurements of some internal contaminations of the detector itself. An analysis of a contamination of 210Po and of the decay of 123Te is presented.
