Heavy Ion Double Charge Exchange Reactions as Probes for Two-Body Transition Densities

Nuclear Theory 2025-06-02 v1

Abstract

Collisional heavy ion double charge exchange (DCE) reactions, induced by second order nucleon-nucleon interactions, are shown to provide access to the two-body transition densities of the complementary DCE transitions in the interacting nuclei. Corresponding two-body operators are introduced, treating the second order distorted wave reaction amplitude in the s-channel interaction form. The theoretical results are applied to the reaction 18O+76Se18Ne+76Ge^{18}O+{}^{76}Se\to {} ^{18}Ne+{}^{76}Ge at Tlab=270T_{lab}=270~MeV, being 76Ge^{76}Ge a candidate for neutrino--less double beta decay.
