Double charge-exchange reactions and the effect of transfer
There is a recently renewed interest on the study of single and double charge exchange reactions with heavy ions. We report here a preliminary theoretical study of double charge exchange reactions in terms of two successive charge exchanges in 2nd order Distorted Wave Born approximation. This allows us to include the effect of the different transfer channels in an approximate way. Evidences show that the charge exchange process is dominant. The following one in importance is the combination of one single charge exchange, one neutron pick-up and one proton stripping. This particular process calls for further investigation. ; Spanish Ministerio de Economía y Competitividad FIS2014-53448-C2-1-P ; FEDER Funds FIS2014-53448-C2-1-P ; Junta de Andalucía 654002 ; European Union 654002
