А program for calculating the double-differential cross section of neutron emission from the (gamma, n) reaction at energies of incident gamma-quanta in the region of а giant dipole resonance has been developed within the framework of а modernized quantum model of giant multipole resonance decay taking account of spins. The model has no free parameters and does not use inverse reaction cross sections in the calculations of neutron emission spectra. The energy and angular distributions of photoneutrons from the Bi(gamma, n) and Au(gamma, n) reactions have bееn calculated for energies of bremsstrahlung gamma-quanta Еgamma,mах = 14.2, 14.9, and 20 MeV. Satisfactory agreement with the experimental data published in the literature is obtained.
