摘要：

The total photoabsorption cross section for carbon and lead has been measured in the energy range 0.5 divided by 2.6 GeV at Bonn using the SAPHIR tagged photon beam. Nuclear data show a significant reduction of the absorption strength with respect to the free nucleon case suggesting a shadowing effect at low energies. (C) 1997 Elsevier Science B.V.
