In this work we study 238U photofission product yields with bremsstrahlung endpoint energy of 19.5, 29.1, 48.3 and 67.7 MeV. The experiment was carried out on an electron racetrack microtron RTM-70 at SINP MSU. A sample was a natural mix of uranium isotopes coating on the aluminum disc. Identification of photofission products and the determination of their quantitative characteristics carried out by gamma spectroscopy. Gamma spectra of the residual activity of the irradiated sample were measured with high - pure germanium detector.
