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 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-detecter estimator of Carter & Cashwell and the GICXFNS group cross section set derived from the ENDF/B-V library. The measured and calculated spectra agreed within the errors estimated from the observed ranges of statistical error and of the folds on spectra due to response function error, except near the resonance peaks of the carbon total cross section at the deeper positions inside pile.
