FACILITY (REAC,1USABNL) Collimated neutron beam of neutrons from1421300100007
BNL pile was chopped into series of 200 microsecond 1421300100008
bursts by slow chopper and filtered by a 4 inches of 1421300100009
Be maintained at liquid N2 temperature to eliminate 1421300100010
neutrons of thermal and higher energies. 1421300100011
SAMPLE Gaseous O2 sample in sample vessel with length of 3.5 m1421300100012
Sample vessel may be evacuated or filled to 10 atm 1421300100013
with O2. Sample temperature was 296 K. 1421300100014
DETECTOR (BF3) Neutrons were detected with a shielded BF3 1421300100015
counter in a good geometry.Chopped beam was monitored 1421300100016
by a BF3 counter placed in a beam obtained from the 1421300100017
same region of the pile as the chopped beam. Monitor 1421300100018
beam was filtered through the graphite. 1421300100019
METHOD (TOF)The velocities of detected neutrons were 1421300100020
determined by time of flight over the 5 m flight path 1421300100021
