DSCE reactions are of second–order distorted wave (DW) character, mediated by isovector nucleon-nucleon (NN) interactions and matrix elements similar to 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.application/pdf6 p.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1393/ncc/i2024-24367-5
