The III phase of experiment TGV-2 to search for β + β + , β+EC, EC/EC decay of 106 Cd was performed at the Modane underground laboratory (LSM, France, 4800 m w.e.). 16 foils (∼23.2 g) of enriched 106 Cd were measured using the 32-detector low background HPGe spectrometer TGV-2 during 42500 h. New limit on 2 ν EC/EC decay of 106 Cd to the ground 0 + state of 106 Pd - T 1/2 > 7.2 × 10 20 y at 90% C.L was obtained. The limits on 2νβ + β + , 2νβ+EC decay of 106 Cd, and 2 ν ECEC decay of 106 Cd to excited states of 106 Pd were significantly improved in comparison with previous phase II of the TGV-2 experiment.
