“…An accuracy of 2% was determined for the PHWT by a detailed study of the possible sources of systematic uncertainties [20]. The PHWT requires coincidence rejection, reliable energy calibration of the γ -ray detection, and a detailed simulation of the experimental setup to determine the WFs.…”

“…This approach has been described in detail in the preceding n TOF analysis of the resolved resonance region [11] together with the justification for the 2% uncertainty taken in this work. The same procedure was also used in previous works [20,[24][25][26][27][28].…”

“…These detectors are optimized to exhibit a very low sensitivity to neutrons, thus minimizing the background produced by neutrons scattered on the sample [22]. The dependence of the detection efficiency on -ray energy and the effect of the -ray threshold of 250 keV were corrected using the pulse height weighting technique [23,24]. By application of a pulseheight dependent weight on the deposited energy, the detection efficiency becomes a linear function of the excitation energy of the compound nucleus, " % k  E c .…”

“…The (n,γ ) cross sections under analysis were measured at the CERN pulsed neutron facility n TOF [21,22]. Neutrons were generated by spallation reactions induced by a beam of 20 GeV protons with a 6-ns pulse width and 0.4-Hz repetition rate in a massive lead target.…”
