Decay studies for neutrino physics. García, A., Sjue, S. K. L., Swanson, H. E., Wrede, C., Melconian, D., Algora, A., & Ahmad, I. Hyperfine Interactions, 223:201-206, Springer Netherlands, January, 2014. Three decades of research using IGISOL technique at the University of Jyväskylä

Both 100Mo and 116Cd are zero-neutrino double-β-decay candidates with J π  = 0 +  and the ground states of the respective intermediate nuclei, 100Tc and 116In, have J π  = 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 of 100Tc 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 of 100Tc and 116In.
