摘要：
Currently, the TGV collaboration is investigating the two-neutrino double electron capture (2 nu EC/EC) of Cd-106 at the Modane underground laboratory. The study is performed with low-background multi-HPGe detector TGV II, which has been constructed for measurements of the rare processes. The half-life limits of T-1/2 > 2.6 x 10(20) years (for Phase I, 8687 hours) and T-1/2 > 3.6 x 10(20) years (for Phase II, 9003 hours) were obtained for the ground state to ground state 2 nu EC/EC of Cd-106. The results already allow to rule out some of the previous nuclear structure calculations.
