Abstract: (AIP)

The theory of heavy ion double charge exchange (DCE) reactions is recapitulated with focus on Double Single Charge Exchange (DSCE) and Majorana DCE (MDCE) reactions. DSCE reactions are of second–order distorted wave (DW) character, mediated by isovector nucleon-nucleon (NN) interactions and matrix elements of a structure as known from 2ν2β decay. The MDCE process proceeds by an induced rank-2 isotensor interaction, given by off–shell pion–nucleon scattering, leading to pion potentials similar to the neutrino potentials in 0ν2β decay.
