AGODI, C. et al. The NUMEN project: Heavy-Ion Double Charge Exchange reactions towards 0νββ NME determination. Nucleus [online]. 2018, n.63, pp. 45-47. ISSN 2075-5635.

NUMEN proposes cross sections measurements of Heavy-Ion double charge exchange reactions as an innovative tool to access the nuclear matrix elements, entering the expression of the life time of Neutrinoless double beta decay (0νββ). A key aspect of the projectis the use at INFN-Laboratori Nazionali del Sud (LNS) of the Superconducting Cyclotron (CS) for the acceleration of the required high resolution and low emittance heavy-ion beams and of MAGNEX large acceptance magnetic spectrometer for the detection of the ejectiles. The experimental measurements of double charge exchange reactions induced by heavy ions present a number of challenging aspects, since such reactions are characterized by very low cross sections. First experimental results give encouraging indication on the capability to access quantitative information towards the determination of the Nuclear Matrix Elements for 0νββ decay.

Keywords : acceleration; charge-exchange reactions; cross sections; detection; double beta decay; heavy ions; ion beams; magnetic spectrometers; nuclear matrix; resolution; superconducting cyclotrons.
