AbstraktAbstract
The studies aimed at decreasing the background of the TGV-2 spectrometer have led to constructive changes in the cryostat and increased the sensitivity of the 32-detector spectrometer. New search for 0vEC/EC, 2vEC/EC) decays of 106Cd was started with ~13.6 g of 106Cd with enrichment of 75%. The evaluation of the experimental data accumulated for 4800 h was performed. Limits (at 90% CL) on the half-lives of 0vEC/EC resonant decay of 106Cd to the 2741 keV excited state of 106Pd (T1/2 ≥ 6.5 × 1019 y) and on t 2vEC/EC decay to the ground state of 106Pd (0+ -> 0+, g.s.) (T1/2 ≥ 1.7 × 1020 y) were obtained. The limits on the other branches of 106Cd decay-2vEC/EC decay to the 2+, 512 keV and 01+, 1334 keV excited states of 106Pd and 2vβ+ β+ and 2vβ+EC decays of 106Cd to the ground and excited states of 106Pd were improved.
