AbstraktAbstract
A new experimental rim of searching for double beta decay of Cd-106 was performed at the Modane underground laboratory (LSM, France, 4800 m w.e.) using the TGV-2 spectrometer, consisting of 32 planar type HPGe detectors with a total sensitive volume of similar to 400 cm(3). 16 foils of Cd-106 with an enrichment of 99.57% and a total mass of similar to 23.2 g were inserted between the entrance windows of face-to-face detectors. The limit on 2vEC/EC decay of (106)cd - T-1/2 > 3.7 x 10(20) y at 90% C.L was obtained from the preliminary calculation of experimental data accumulated for 8198 h of measurement. The limits on the resonance OvEC/EC decay of Cd-106 were obtained from the measurement of similar to 23.2 g of Cd-106 with the low-background HPGe spectrometer Obelix lasted 395 h -T-1/2 (KL, 2741 keV) > 0.9 x 10(20) y and T-1/2 (KK, 2718 keV) > 1.4 x 10(20) y at 90% C.L.
