Parameter-Estimation For Hydrogen Analysis By Using Transport Method

A transport method is described which reduces greatly the number of calibration standards needed for hydrogen analysis by neutron induced prompt gamma-rays. The counts in the photopeaks from neutron capture in hydrogen for various standard concentrations, the distribution of the source neutron rate entering the thermal group and the reaction rates in the samples are investigated theoretically using 100 energy group cross sections and experimental Cf-252 spectra for a test configuration. Comparison of theoretical results with those measured from the test configuration shows good agreement.
