TITLE Cross-section measurements in the intermediate- 1315300100007
energy standard neutron field 1315300100008
FACILITY (REAC,1USANBS) NBS 20 MW research reactor + U235 disks 1315300100009
INC-SOURCE Fission spectrum, 235U 1315300100010
INC-SPECT ISNF spectrum, resembles fast reactor spectrum, but 1315300100011
has less complex structure. Median energy = 0.58 MeV. 1315300100012
98% of fluence between 1.2 keV and 5.6 MeV. 1315300100013
COMMENT The ISNF spectrum is available in IRDF-2002. 1315300100014
METHOD (ACTIV) 1315300100015
DETECTOR (GE-IN) 1315300100016
MONITOR 252Cf/235U ratio for 140Ba-140La count rate is 0.772, 1315300100017
which gives the FLUENCE transfer 1315300100018
