AbstraktAbstract
The III phase of experiment TGV-2 to search for β+β+, β+EC, EC/EC decay of 106Cd was performed at the Modane underground laboratory (LSM, France, 4800 m w.e.). 16 foils (~23.2 g) of enriched 106Cd were measured using the 32-detector low background HPGe spectrometer TGV-2 during 42500 h. New limit on 2νEC/EC decay of 106Cd to the ground 0+ state of 106Pd - T1/2 > 7.2 × 1020 y at 90% C.L was obtained. The limits on 2νβ+β+, 2νβ+EC decay of 106Cd, and 2νECEC decay of 106Cd to excited states of 106Pd were significantly improved in comparison with previous phase II of the TGV-2 experiment.
