SAMPLE 232Th and 237Np targets of thicknesses 1.8 mg/cm2 and D612900100011
300 ug/cm2 respectively on aluminium backing. D612900100012
DETECTOR (SIBAR) Two silicon surface barrier detectors of D612900100013
thickness 12 micrometer at 110 and 160 degree with D612900100014
respect to the beam direction to detect the fission D612900100015
fragments D612900100016
(SCIN) Two NE213 neutron detectors (5 cm thick and 5 cmD612900100017
in diameter) at a distance of 50 cm from the target D612900100018
each subtending angles of 0 or 180 degree, and 90 D612900100019
degree with respect to the direction of fragment D612900100020
detection. D612900100021
METHOD (TOF) The time of flight signal of each neutron D612900100022
detector was obtained with reference to the start D612900100023
pulse derived from either of the 2 fission detectors. D612900100024
ANALYSIS The laboratory neutron energy spectra were determined D612900100025
from the observed time-of-flight spectra after D612900100026
correcting for the neutron detection efficiency for D612900100027
each neutron detector. D612900100028
