Gamma-ray production double-differential cross sections have been measured for 0.8, 1.5 and 3.0 GeV protons incident on C, Al, Fe, In and Pb targets. Gamma-rays were detected by NEZ13 liquid scintillators and gamma-ray signals were separated from neutron ones by a two-gate integration method. The photomultiplier-charge data of gamma-rays were unfolded with the FERDo-U code. Because of rather thick targets, effects of secondary particles on gamma-ray generation had to be removed and they were evaluated by particle transport calculations with the NMTC/JAERI, MCNP4A and HETC-KFAZ codes. Attenuation of gamma-rays in the target was calculated by the EGS4 code. Gamma-ray production cross sections were obtained in a gamma-ray energy range up to 60MeV. The experimental results were compared with calculated values by the HETC-KFAZ code. At gamma-ray energies up to 10MeV, the calculated cross sections agree with experimental data for the Fe, In, and Pb targets typically within a factor of two.
