The study of heavy-ions induced double charge-exchange (HI-DCE) nuclear reactions is a promising way to access data-driven information on neutrino-less double-beta decay nuclear matrix elements. In the following, particular attention is given to the ( 18 O, 18 Ne) and ( 20 Ne, 20 O) HI-DCE reactions as tools for β + β + and β − β − decays, respectively. The experiments are performed in Catania at the Laboratori Nazionali del Sud of the Istituto Nazionale di Fisica Nucleare (INFN-LNS). The MAGNEX magnetic spectrometer is used to momentum analyse the ejectiles of a large network of nuclear reactions. New preliminary experimental data for the 76 Se( 18 O, 18 F) 76 As and 76 Ge( 20 Ne, 20 F) 76 As single charge exchange (SCE) and for the 76 Se( 18 O, 18 Ne) 76 Ge and 76 Ge( 20 Ne, 20 O) 76 Se DCE nuclear reactions were also investigated.
