摘要：

A new series of measurements with a proportional-drift detector containing 210 g of Xe-136 in the sensitive volume was carried out. The background, related to Rn-222 (U-238 family), was reduced by more than an order of magnitude. Another background caused by external gamma-radiation in the hall where the equipment was installed, was studied. Using 10 cm Pb shielding, we reduced the background from external gamma-radiation. A half-life limit of T1/2(2-beta-2-nu) > 9.3 X 10(19) yr (90% CL) was obtained.
