Abstract: Using gamma-spectroscopic methods, comparative measurements of (γ, n) reaction yields on the isotopes 140Се and 142Се were carried out in the energy region of 9 - 18 MeV using gamma-quanta. It was shown, that for the isotopes of Cerium using the quasimonochromatic beams of photons [1] the error of the measurement of the (γ, n) reaction cross section due to the contribution of the (γ, 2n) reaction did not exceed 2%.

Keywords: nuclear reaction cross section, gamma-quanta, 140Ce, 142Ce, microtron.
