This page provides access to the incident-neutron evaluations for ENDF/B-VII. Each entry has links to the raw ENDF evaluation, to an interative browser that makes it easier to read ENDF format for non experts, and to PDF plots of the data that were generated during processing for an MCNP library. In addition, each entry has supplemental information, including the ENDF MAT number and an "Info Tag" which provides some summary information about the contents of the evaluation using the following abbreviations: B = Single-level Breit-Wigner resolved resonance parameters M = Multi-level Breit Wigner resolved resonance parameters R = Reich-Moore resolved resonance parameters A = Adler-Adler resolved resonance parameters G = General R matrix resonance parameters U = Single-level Breit-Wigner unresolved resonance parameters 4 = File 4/5 present 6 = File 6 present g = Gamma production from file 12-15 or file 6 present c = Covariance files present Elem Iso MAT Info Tag Links 1-H -1 125 ---46-g- raw eval view PDF plots -2 128 ---46-g- raw eval view PDF plots -3 131 ---4--g- raw eval view
