Search for double beta decay of 106Cd in the TGV-2 experiment
Original language description
An investigation of double beta decay (Beta+Beta +, Beta+/EC, EC/EC) of 106Cd was performed at the Modane underground laboratory (at a water equivalent depth of 4800 m) using a TGV-2 spectrometer with 32 detectors. Evaluation of the experimental data accumulated over 12 400 h of measuring cca 13.6 g of 106Cd with an enrichment of 75% was performed. New limits (at a confidence level of 90%) on the half-lives of the 0?EC/EC resonant decay of 106Cd to the 2741 keV excited state of 106Pd - T 1/2 >= 1.5 x 1020 y and on 2?EC/EC decay to the ground state of 106Pd (0+ -> 0+, g.s.) - T 1/2 >= 3.9 x 1020 y were obtained. The limits of the 2?EC/EC decay of 106Cd to the 2+, 512 keV and 0 1+, 1334 keV excited states of 106Pd and 2vBeta+Beta+- and the 2?Beta+ EC decays of 106Cd to the ground and excited states of 106Pd were improved.
