The ENDF/B-VIII.1 release is the newest evaluated nuclear data library produced, distributed, and recommended by CSEWG for use in nuclear science and technology applications.

6 Presentation name 3. Horace platform • One of the two preferred methods for data reduction and analysis – at the SNS Sequoiah – double diff. (angle, energy) cross section is reduced to S(q,ω) – Built-in function for parameter fitting to reduced data S(q,ω) • Returns model parameters, their uncertainties, and the correlation matrix

Description: Nuclear Data Sheets is a journal primarily devoted to the publication of evaluated nuclear structure and decay data, that is, recommended values following a careful compilation and analysis of all available experimental results dealing with nuclear properties such as:

Nuclear Science References (NSR) NSR Reference Paper NIM A 640, 213 (2011) NSR Coding Manual () The NSR database is a bibliography of nuclear physics articles, indexed according to content and spanning more than 100 years of research. Over 80 journals are checked on a regular basis for articles to be included.
