Abstract

The measurement of the 116Sn(18O, 18Ne)116Cd double charge exchange reaction cross section at very forward angles was performed for the first time at INFN-LNS using the MAGNEX magnetic spectrometer. This study, carried out at 276 MeV beam energy, provides a cross section of 34 nb ([9, 44] nb at 95% confidence level), confirming the tiny values recently obtained for the same reaction in other nuclides. This result has a major impact on the forthcoming systematic investigation of 0νββ decay candidates carried out by the NUMEN project, since it allows to properly tailor future experiments with high-intensity beams. The ultimate goal of this exploration is to experimentally access information about nuclear matrix elements relevant to the 0νββ decay rate.
