Preliminary results on double beta decay of 1 3 0 Te obtained in the first run of an array of twenty cryogenic detectors are presented. The set-up is made with crystals of TeO 2 of 340 grams each corresponding to the largest presently operating cryogenic mass. It was run under a heavy shield in the Gran Sasso Underground Laboratory at a depth of about 3500 m.w.e. By recording the pulses of each detector in anticoincidence with the others a 90% c.l. lower limit of 5.6x10 2 2 years has been obtained on the lifetime for neutrinoless double beta decay of 1 3 0 Te in a preliminary test run, corresponding to about one week of effective running time. No evidence is also found for double beta decay to the first excited 2 + state of 1 3 0 Xe with a 90% c.l. lower limit of 1.7x10 2 2 years on that lifetime. Some consequences of the present results in the interpretation of geochemical experiments are discussed.
