Description

Line of γ-radiation of the energy Eγ=11.3 MeV was detected during experimental researches at nuclear reactor on the investigation into characteristics of energetic spectrum of γ-quanta following by the process of fission in the range of energy >10 MeV. The most probable source of this line is a consequence of radiation capture reaction of thermal neutrons at nuclei 59Ni accumulated in corrosion-resistant steel as a result of more than 20-years irradiation in the reactor because of reaction 58Ni(n, γ)59Ni. As it was determined the concentration of 59Ni comprised 0.47% of the concentration of 58Ni nuclei on thermal neutron fluence of 1021 cm -2

Abstract (Russian)

В ходе выполнения эксперимента на ядерном реакторе по исследованию характеристик энергетического спектра γ-квантов, сопровождающих процесс деления в области энергии >10 МэВ, обнаружена линия γ-излучения энергией Eγ=11.3 МэВ. Наиболее вероятным источником этой линии является реакция радиационного захвата тепловых нейтронов на ядрах 59Ni, накопившихся в коррозионно-стойкой стали в результате более чем 20-летнего облучения в реакторе вследствие реакции 58Ni(n, γ)59Ni. Определено, что при флюенсе тепловых нейтронов 1021 см -2 концентрация 59Ni составляет 0.47% концентрации ядер 58Ni
