Abstract: | Recommended k
0-factors for gamma-lines of 24 elements useful for neutron-induced prompt gamma-ray analysis (PGA) and which are not influenced
by neutron spectrum differences were obtained from the k
0-factors measured with the cold and thermal neutron guided beams of JRR-3M, by statistical calculation. The prompt gamma-ray
emission probabilities were derived from the recommended k
0-factors using atomic weight, isotopic abundance and thermal neutron capture cross section all related to the k
0-factors, for which one can obtain accurate data. The derived gamma-ray emission probabilities for the light elements (H to
Ca) agreed well within ±10% with those of the ENSDF values, which reflect recent data while the agreement for heavy elements
(Ti to Pb) was ±40% with those of the ENSDF, which are still composed of old data.
