Description
We have used the (d,2He) reaction to obtain the GT+ strength distribution for 116Sn →116In transitions. Here, 116In is the intermediate nucleus in the second-order perturbative description of 116Cd double beta (ββ) decay. In this paper we will review what is known about the nuclear matrix elements for the 116Cd 2νββ decay, discuss the single-state dominance hypothesis and combine our new data with other existing data from charge-exchange reactions to obtain a 2νββ-decay half-life. The deduced value T1/2=(4±1)x1019y compares well with the one known from direct counting experiments
