Gamma-ray production double-differential cross sections have been measured for 1.5 GeV π+ meson incidence on iron target. Gamma-rays were detected by NE213 liquid scintillators and were separated from neutron events by a two-gate integration method. The experimental results were compared with calculated values by the HETC-KFA2 code that takes account of in-medium effects. At γ-ray energies up to 7 MeV, the calculated cross sections agree with the experimental data typically within a factor of 2. The measured data were also compared with proton incidence ones. The γ-ray emission cross sections for 1.5 GeV π+ meson incidence tend to be larger than those for proton incidence in the energy region above 4 MeV.
