Background: Single-charge-exchange reactions are appropriate tools to study the nuclear response one-particle/one-hole isospin probes, gaining additional interest from connection beta decay. This analogy has been recently extended second order, connecting double-charge-exchange and double decays. Nowadays, availability of powerful experimental setups advanced theories models allows one access precious information on key structure aspects embedded in widely sought neutrinoless decay.Purpose:...

Single-nucleon transfer reactions are processes that selectively probe single-particle components of the populated many-body nuclear states. In this context, recent efforts have been made to build a unified description rich spectroscopy accessible in heavy-ion collisions. An example multichannel approach is study competition between successive nucleon and charge exchange reactions, latter being particular interest context single double beta decay studies. To extent, one-proton pickup...
