Times Cited Count:9 Percentile:52.57(Chemistry, Analytical)The recommended k factors for 81 -lines of 24 elements, which are useful for neutron induced prompt -ray analysis (PGA) and are not influenced by neutron spectrum difference, were obtained from the k factors measured with the cold and thermal guided neutron beams of JRR-3M by statistical calculation. The prompt -ray emission probabilities were derived from the recommended k-factors using atomic weight, isotopic abundance and thermal neutron cross-section of other nuclear constants consisting the k factors, for which one can obtain accurate data. The derived -ray emission probabilities for the light elements (H to Ca) well agreed within 10% with those of the ENSDF, which reflect recent data, which the agreements for heavy elements (Ti to Pb) were 40% with those of the ENSDF, which are still composed of old data.
