Neutron flux was determined by 3047000100019 associated particle method. The absolute efficiency of 3047000100020 the neutron detector was experimentally determined from3047000100021 its response to the known flux of monoenergetic 3047000100022 neutrons. (See Waheed et al.,Pinstech Int.Rep.No.5(NPD)3047000100023 (FNPG). Then the measured efficiency was fitted to 3047000100024 the value obtained with Monte Carlo calculation. 3047000100025 The side experiment of carbon breakup was used to 3047000100026 verify the efficiency curve. 3047000100027 PART-DET (N) 3047000100028 STATUS (APRVD) Approved by K.Gul with amendment,79/05/14. 3047000100029 HISTORY (19790406C) KO. 3047000100030 (19790619A) KO.-'Aprvd' added.
