Abstract
A finite half-life of T-1/2(2v) = 2.6(-0.5)(+0.9).10(19) yr(68%CL) for the two neutrino double beta decay of Cd-116 to the ground state of S n-116 was found for the first time by means of the ELEGANTS V detector . Nuclear matrix elements for the two neutrino double beta decay was d educed as M(2v) = (0.073 +/- 0.010)m(e)(-1) from the measured half lif e. A stringent lower limit on the half life of neutrinoless double bet a decay of Cd-116 to the ground state in Sn-116 was obtained as T-1/2( 0v) > 5.4 x 10(21)yr (68%CL).
