Comparative measurements and analysis of detection efficiency of fast and thermal neutrons from ²³⁹Pu-Be source by heavy oxide scintillators (Z≥50) confirmed high detection efficiency (∼ 40-50 %). The most probable mechanism determining the fast neutron detection efficiency is the reaction of inelas...
