INC-SOURCE (P-LI7) 7Li(p,n)7Be reaction 2006000100009
INC-SPECT (EN-RSL-HW) neutron energy spread 2006000100010
SAMPLE (92-U-238,ENR=0.9927) 2 cm diameter sphere of 2006000100011
natural uranium 2006000100012
METHOD (TOF) Standard time of flight technique. The scattering2006000100013
sphere was placed 60 mm from the target and the 2006000100014
detector about 210 mm from the scatterer in 105 deg. 2006000100015
(BCINT) Two methods were used for monitoring of the 2006000100016
incident neutron flux, viz. beam current integration 2006000100017
and a LiI-polythene counter, the latter being placed 2006000100018
well within the cone of neutron emission to avoid undue2006000100019
dependence on fluctuations of the proton energy, and 2006000100020
further at a position such as to eliminate any possible2006000100021
interference from scattering. 2006000100022
DETECTOR (SCIN) 6Li glass scintillation detector 2006000100023
CORRECTION .The general background of neutrons scattered by the 2006000100024
target assembly and the surrounding air was subtracted2006000100025
from the 92-U-238 and 82-Pb spectra. 2006000100026
.The flat background corresponding to the natural radio2006000100027
activity was further subtracted from the U238 spectrum2006000100028

ERR-ANALYS (ERR-S) Statistical error 2006000300010
By far the most important contribution to the total 2006000300011
error is due to the background of air-scattered 2006000300012
neutrons compared to which the other terms are 2006000300013
practically negligible. 2006000300014
