weight 328.5 g 3071600100013
MONITOR (1-H-1(N,EL)1-H-1,,DA) 192.1 mb/sr, at 25 degree, 3071600100014
were taken as reference. Polyethylene was used. 3071600100015
FACILITY (CCW,3CPRAEP) 3071600100016
INC-SOURCE (D-T) 3071600100017
METHOD (ASSOP,TOF) Flight path 3 m, time resolution at 14.2 3071600100018
MeV neutron energy is about 1 nsec. 3071600100019
DETECTOR (SCIN) Liquid, 105*50 mm, ST-451 type. China made. 3071600100020
ERR-ANALYS (ERR-T) Total error is in the range of 4-11%. 3071600100021
Errors of the experimental data are mainly, 3071600100022
(ERR-1) Uncertainty in weight for uranium and 3071600100023
hydrogen - 0.5% 3071600100024
(ERR-2) 0.5% Uncertainties in dead time correction, 3071600100025
primary neutron spectrum and detector efficiency 3071600100026
correction - 0.5% 3071600100027
(ERR-3) Uncertainties in neutron flux 3071600100028
attenuation, multiscattering and geometrical 3071600100029
corrections - 1.2% 3071600100030
(DATA-ERR,2.,4.) Statistics, and standard deviation 3071600100031
of scattering neutron counting - 2-4% 3071600100032
(ERR-S) Statistics of n-p scattering neutron 3071600100033
counting - 3% 3071600100034
ANALYSIS Due to limitation of energy resolution the elastic 3071600100035
scattering angular distribution measured includes the 3071600100036
contribution from low level (below 1 MeV) inelastic 3071600100037
scattering. 3071600100038
