Double-charge exchange (DCE) reactions are the object of a worldwide renewed interest, also for the information that one could extract on the nuclear matrix elements entering the expression of the life time of the double beta decay. This possibility is essentially based on the coincidence of the initial and final state wave-functions in the two classes of processes and the similarity of the transition operators, which in both cases present a given superposition of Fermi, Gamow-Teller and rank-two tensor components with a relevant implicit momentum available.
An intense experimental activity on double charge exchange reactions is planned at the LNS-Catania, according to the NUMEM project. The aim of the workshop is to critically discuss the status of the art and possible future developments of the theoretical models of DCE reactions, as well as the crucial aspects of the experimental techniques and analyses. A central point would be the identification of the experimental conditions more suitable to extract, by comparison with the model predictions, the nuclear matrix elements of the DCE process. We also aim at dedicating critical discussions to the analogy between the theoretical description of the neutrino-less double beta decay, and of double charge exchange reactions, to point out differences and similarities between the two processes.
