The cross section for the photoproduction of pi-zero mesons from complex nuclei at small angles has been measured at incident bremsstrahlung energies of 4.4 and 6.6 GeV. The data are fitted by a cross section calculated from a sum of Primakoff and nuclear-production amplitudes. A total decay width for the pi-zero meson of 8.02±0.42 eV is obtained from the magnitude of the Primakoff amplitude.
