The idea of NUMEN project is to study heavy-ion induced Double Charge Exchange (DCE) reactions with the aim to get information on the nuclear matrix elements for neutrinoless double beta (0νββ) decay. To infer the neutrino average masses from the possible measurement of the half-life of 0νββ decay, the knowledge of the nuclear matrix elements is crucial. DCE reactions and 0νββ decay present some similarities, the initial and final-state wave functions are the same and the transition operators are similar. The experimental measurements of DCE reactions induced by heavy ions present a number of challenging aspects, since they are characterized by very low cross sections. © Copyright owned by the author(s) under the terms of the Creative Commons.
