[en] The purpose of the paper was to obtain calibration absolute values of the neutron capture to-fission rati αn for 235U resonances. Measurements were conducted by the method of spectrometry of multiplicity of excited nuclear radiation on a 26-meter path length of an electron linear accelerator by a 48-section NaI(Tl) scintillation detector with a 10B convertor. The α values for 15 resonances in the 3.61-32.07 eV energy range were obtained. The error in α determination is 2%

[en] An absolute measurement of the neutron-capture-to-neutron-fission cross section ratio (alpha value) at the Uranium-235 resonances has been performed. For most resonances the accuracy is better than 2% which considerably exceeds that of the available alpha values. (Auth.)
