Abstract

Both100Mo and116Cd are zero-neutrino double-β-decay candidates with Jπ= 0+and the ground states of the respective intermediate nuclei,100Tc and116In, have Jπ= 1+. This makes it possible to measure these matrix elements, which turn out to provide a valuable benchmark for testing models. The electron-capture (EC) decay of100Tc can also be used to directly determine the efficiency of a potential neutrino detector. However, the experimental determinations of the EC decay branches of interest are challenging because they are only small fractions of the main decays and co-produced radioactivities contribute significant background counts in the regions of interest. This article summarizes our work at Jyväskylä, where we have taken advantage of the high-purity beams produced at IGISOL in combination with JYFLTRAP to achieve significant improvements in the determinations of the EC branches of100Tc and116In.
