“…Of this time, up to 250 msec may be spent in a loop waiting for the Nuclear Data analyzer to generate an LCHO pulse. Many sophisticated programs for the reduction of Ge(Li) spectra have been published [13][14][15][16][17][18][19][20]. Techniques used in a number of these computer codes have been incorporated in our own routines.…”

The spectrometer system developed in this work consists of a Ge(Li) detector and a 4096-channel multichannel analyzer interfaced directly to a computer with 16,384 24-bit words. The restrictions imposed by a medium-sized core have been circumvented by performing the data reduction in successive steps which are called from a disk file while the data remain in core. Since the analyzer memory is not used to store data during reduction, new data can be acquired while data reduction is in progress.The disk file includes routines for energy calibration, efficiency calibration for each of the geometries used in counting, smoothing, and peak location and integration. The output options include linear or semilogarithmic plots of the spectra. Calibration in the energy region 40-1600 keV is done with a mixed source 57 Co, I37 Cs, and 60 Co. Since the samples are routinely irradiated under reproducible conditions in the same reactor, the flux can be derived from a single flux value obtained from a gold and cobalt monitor.Analysis of standard mixtures indicates an accuracy ranging from ±4.9 to ±7.5%, depending on the counting statistics.

“…One can smooth not the first or second derivatives but the original data and establish the sign of the first derivative by simply comparing consecutive channels. To increase statistical reliability, one demands not only N i > N i−1 , but also N i+1 > N i [5]. As is claimed in [6], for low statistics the best result is given by the following smoothing…”
