J. Jordanova et al., Measurements and calculations of neutron spectra modified by iron slabs bombarded by neutrons with energies up to 14 MeV, APPL RAD IS, 54(2), 2001, pp. 307-310
Neutron spectra behind iron slabs of different thicknesses have been measur
ed in the energy range from 1.6 to 14 MeV using a proton recoil spectromete
r and H-2(d, n)He-3 and Be-9(d, n)B-10 neutron sources. The measured result
s have been compared with the predicted ones using the three dimensional Mo
nte Carlo code MCNP 4A and pointwise cross sections from the ENDF/B-IV and
ENDF/B-VI data files. The results show that the ENDF/B-IV calculations are
in better agreement with the experiment than those obtained by using the EN
DF/B-VI cross section data. (C) 2001 Elsevier Science Ltd. All rights reser
