We extract the relative importance of the different exchange mechanisms included in the meson picture by means of a comparison to the corresponding operational structures appearing in the effective approach. The ability of this procedure to obtain the weak baryon-baryon-meson couplings for a possible scalar exchange is also discussed.9 p.application/pdfeng(c) American Physical Society, 2011Física nuclearReaccions nuclearsNuclear physicsNuclear reactionsinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
