Behavior Of The Be And C Total Photonuclear Cross-Section In The Nucleon Resonance Region

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 [Delta]. We used a tagged photon beam and the transmission technique. The results show no evidence of baryon resonances that are clearly seen at [approx]700 and [approx]1000 MeV in photon absorption on the proton and the deuteron.
