The scalar neutron spectrum normalized in reference to unit source neutron was meas-ured with a miniature NE213 spectrometer at several positions along the centerline in a graphite-reflected lithium fluoride pile irradiated with D-T neutrons. The measured spectra were compared with the results of calculation using the MORSE-GG Monte Carlo code with the modified point-detector estimator and the GICXFNS group cross section set. The calculated spectrum near source neutron peak was less than the measured spectrum, and the discrepancy became larger with increasing penetration distance in the lithium fluoride region. The calculated spectrum was less than the measured spectrum below 4 MeV, especially in the graphite region.
