INC-SPECT Thermal spectrum of moderated neutrons 4137700100018
DETECTOR (TELES,PROPC,PROPC) Battery of 12 He-3 counters 4137700100019
METHOD Periodic irradiation of the sample with an irradiation 4137700100020
frequency of 1.25 Hz, which was achieved by reducing 4137700100021
the rotation frequency of the chopper. 4137700100022
The data were accumulated over 40 hours for 235U and 4137700100023
86 hours for 239Pu. 4137700100024
CORRECTION Background was determined by measurements with a Cd 4137700100025
filter in the beam, amounted to no more than 1% of the 4137700100026
total neutron count. 4137700100027
