Abstract

Experimental verification for correctness of registration for delayed neutrons from 238U photofission is described for the maximum energy of bremsstrahlung γ-quanta ≅10 MeV at the pulsed linear electron accelerator LUE-8-5 in an interval of (1–5) ms after each beam pulse in time ≳7 min from start of irradiation. The measurements were carried out using the scintillation spectrometer for fast neutrons based on a stilbene single crystal with pulse shape discrimination for scintillations from γ-quanta and fast neutrons. The time dependence of counting rates of delayed neutrons from 238U photofission was measured at a repetition rate of 300 s-1 in intervals of (1.25–3.30) ms.
