MONITOR (79-AU-197(N,G)79-AU-198,,SIG) 2306500100041
METHOD (TOF) The incident neutron energy spectrum on the 2306500100042
capture sample was measured by means of a 2306500100043
time-of-flight (TOF) method 2306500100044
(SITA) Intermittent single target cyclic irradiation 2306500100045
of samples (Se-74 - 41 hour, gold monitor 13 hour 2306500100046
and blank sample 6 hour) to average out changes 2306500100047
in experimental conditions. 2306500100048
.A pulse-height weighting technique was applied 2306500100049
to the observed capture gamma-ray pulse-height 2306500100050
spectra to obtain the capture yields. 2306500100051
