We present the total photonuclear cross section for Be and C measured between 200 and 1100 MeV, with the aim of clarifying the existence of a resonant behavior in the region above the Δ. We used a tagged photon beam and the transmission technique. The results show no evidence of baryon resonances that are clearly seen at ≊700 and ≊1000 MeV in photon absorption on the proton and the deuteron.

Abstract
We present the total photonuclear cross section for Be and C measured between 200 and 1100 MeV, with the aim of clarifying the existence of a resonant behavior in the region above the Δ. We used a tagged photon beam and the transmission technique. The results show no evidence of baryon resonances that are clearly seen at ≊700 and ≊1000 MeV in photon absorption on the proton and the deuteron.
