We present the results of measurements of the total photonuclear absorption in light medium-heavy and heavy nuclei carried on at Frascati with 200-1200 MeV monochromatic photons, to obtain information on the behavior of baryon resonances in nuclei and on the possible onset of the shadowing effect. Preliminary results obtained from Be and C, using the transmission technique, and from U using the photofission method show no evidence of baryon resonances at about 700 and about 1000 MeV seen in the photon absorption on the proton and the deuteron.

Abstract
We present the results of measurements of the total photonuclear absorption in light medium-heavy and heavy nuclei carried on at Frascati with 200-1200 MeV monochromatic photons, to obtain information on the behavior of baryon resonances in nuclei and on the possible onset of the shadowing effect. Preliminary results obtained from Be and C, using the transmission technique, and from U using the photofission method show no evidence of baryon resonances at about 700 and about 1000 MeV seen in the photon absorption on the proton and the deuteron.
