Abstract

The present work is inherent to the NUMEN project that aims at providing data-driven information for the nuclear matrix elements of the neutrinoless double beta decay through the study of heavy-ion induced double charge exchange reactions. This is a formidable task since during a nuclear collision, the same final states may be populated through various reaction mechanisms. In this respect, understanding the degree of competition between successive nucleon transfer and charge exchange reactions is crucial for the proper description of the meson-exchange mechanism. To this purpose, the reaction dynamics in the ¹⁸O+⁴⁸Ti collision were sought by measuring a plethora of reaction channels under the same experimental conditions. The ⁴⁸Ti was chosen as target since it is the daughter nucleus of ⁴⁸Ca in double beta decay. The relevant experiment was performed at the MAGNEX facility of INFN-LNS in Catania. In this contribution, the status of the analysis for the ⁴⁸Ti(¹⁸O,¹⁸F)⁴⁸Sc single charge exchange reaction will be presented.
