摘要：

The total cross section of hadron photoproduction on C, Cu and Pb nuclei is measured for six energy values in the range 12-30 GeV. The obtained cross-section values for C and Cu nuclei have a weak energy dependence at high energies (above 20 GeV). The cross section for the Pb nucleus is somewhat higher in comparison with that expected, and energy dependence is not observed. The A-dependence of the effective number of hadrons agrees with VDM predictions. © 1978.
