This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Independent databases of nuclear constants for Neutron Activation Analysis (NAA) have been independently maintained by the physics and chemistry communities for many year. They contain thermal neturon cross sections s0, standardization values k0, and transition probabilities Pg. Chemistry databases tend to rely upon direct measurements of the nuclear constants k0 and Pg which are often published in chemistry journals while the physics databases typically include evaluated s0 and Pg data from a variety of experiments published mainly in physics journals. The IAEA/LBNL Evaluated Gamma-ray Activation File (EGAF) also contains prompt and delayed g-ray cross sections sg from Prompt Gamma-ray Activation Analysis (PGAA) measurements that can also be used to determine k0 and s0 values. As a result several independent databases of fundamental constants for NAA have evolved containing slightly different and sometimes discrepant results. An IAEA CRP for a Reference Database for Neutron Activation Analysis was established to compare these databases and investigate the possibilitiy of producing a self-consistent set of s0, k0, sg, and Pg values for NAA and other applications. Preliminary results of this IAEA CRP comparison are given in this paper.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this work was fivefold: to develop an expanded neutron cross-section library containing approximately 1200 cross-section sets with the Hansen-Roach (H-R) sixteen neutron-energy-group structure; to provide an enhanced computational tool on a personal computer for criticality calculations; to provide consistent values of the effective scattering cross sections (sigma-s) for each set of the expanded H-R library, for selecting the resonance self-shielded cross sections (sigma-p); to develop a consistent technique for calculating sigma-p to select and apply specific self-shielded cross-section sets; and to apply the cross sections and the selection technique to a wide variety of criticality calculational benchmarks. 18 refs., 1 fig.

Available in PDF, EPUB and Kindle. Book excerpt: Because of recent advances in experimental techniques, which improved the accuracies of thermal capture and scattering cross sections by an order of magnitude, a more stringent approach in the evaluation of the thermal constants is developed. In the present approach, the following aspects are introduced: (1) a consistency between thermal cross sections, coherent and incoherent scattering lengths, and neutron resonance parameters is achieved; (2) a consistency between the isotopic and element cross sections is sought; in addition, for each isotope, the requirement that the partial cross sections add up to the total is fulfilled; (3) where possible, charged particle data particularly derived from (d, p) reactions on light and medium weight isotopes are used in locating the positions and strengths of bound levels. Such a procedure is useful in the evaluation of the shape of the cross sections in the thermal region; and (4) the Lane-Lynn theory of direct capture is called upon to calculate thermal cross sections and check for consistencies for certain isotopes. Extensive examples to illustrate these procedures are presented.
