ENDF/B Summary Documentation
摘要
The purpose of this publication is to provide a localized source of descriptions for the evaluations contained in the ENDF/B Library. The summary documentation presented in this volume is intended to be a more detailed description than the (File 1) comments contained in the computer readable data files, but not as detailed as the formal reports describing each ENDF/B evaluation. (A list of the published formal reports is given in the table of contents.) The summary documentations were written by the CSEWG (Cross Section Evaluation Working Group) evaluators and compiled by NNCSC (National Neutron Cross Section Center). When assembling the information for this volume, a minimum amount of editing was unavoidable. This editing primarily consisted of removing computer file listings and irreproducible graphs, since these can be easily obtained from the ENDF files with the use of standard editing or plotting programs. In a few instances, sections of the formal document were reproduced. Materials for which no summary documentation has been received to date, are represented by the (File 1) comments contained in the data file only. The loose leaf-independent section format was selected for ease of updating when more documentation and/or evaluations become available. It is hoped that In the future a more standardized documentation will make the updating simplified. The publication is presented in sections, each section describing one (or more) ENDF evaluations. These sections are identified and ordered by element number (Z) and atomic weight (A). Sections describing more than one ENDF material are identified by the Z-A numbers of the lowest material described. The section number corresponding to a particular data set should be determined using the table of contents. (e.g., <sup>6</sup>Li(MAT-1115) is described in Section 3-6, whereas <sup>133</sup>Cs(MAT-1141) is described in Section 47-107, which also includes <sup>107</sup>Ag and <sup>109</sup>Ag.)
