The results of new measurements of gamma-ray production cross sections and spectra in inelastic interaction of 14 MeV neutrons with nuclei C, O, Mg, Al, Fe, Cu, Zr, Mo, W, Pb are discussed. The measurements were carried out for the gamma-ray energy interval of 0.5-14 MeV using the pulsed neutron source and scintillation gamma-spectrometer combined with the time-of-flight technique. Parameters of the used samples, the geometry and conditions of measurements are described. The corrections connected with the multiple scattering of neutrons and gamma-rays in samples and the contribution of gamma-rays from the neutron target are taken into consideration. The total and differential gamma-ray production cross sections are given for all samples together with their uncertainties. The estimated uncertainty of the total production cross sections is about 9% for the confidence probability level of 0.95.
