At photon energies around the pion production threshold we obtain a fraction of three body absorption of less than 10% of the total, contradicting previous theoretical claims that it dominates the absorption process. The strength of the three body channel grows smoothly with the photon energy reaching a maximum of about 60% of the total direct absorption at energies of the photon around 400 MeV.9 p.application/pdfeng(c) The American Physical Society, 1996Reaccions nuclearsAbsorcióFotonsNuclear reactionsAbsorptionPhotonsinfo:eu-repo/semantics/article112204info:eu-repo/semantics/openAccess
