Investigation metods and technique: neutron spectrometry using gas-filled recoil counters; technique for total neutron cross section determination by neutron transmission measurements of experimental samples. Design modelling based on ENDL has been done for determination of optimal neutron filter compositions with energies 2 to 147 keV, experimental investigations of neutron filter properties has been fulfilled to get the neutron beams with energies 2 to 147 keV, average total neutron cross sections for Hf are determined experimentally for energies in the region 2 to 147 keV, calculations of Hf averaged neutron cross sections has been done using ENDL data. Analysis has been done of the received experimental results for Hf averaged total neutron cross sections measuted at neurton filtered beams with averaged energies 2; 54; 59 and 147 keV and also the comparison with the cross sections in ENDL and EXFOR, the recommendations have been done for improvement of Hafnium ENDF as structure material.5481 Product Description popup.authors Венедиктов Віталій Михайлович Волковецький Степан Петрович Ворона Петро Миколайович Гримало Анна Костянтинівна Грицай Олена Олександрівна Кальченко Олександр Іванович Лібман Володимир Абрамович Разбудей Володимир Федорович popup.nrat_date 2020-04-02 Close
