Status of the Atlas of Neutron Resonances

The \textit{Atlas of Neutron Resonances} is the most comprehensive compilation of neutron resonances, thermal cross sections, resonance integrals and Maxwellian averaged cross sections generally available. For decades, the \textit{Atlas} was carefully curated and maintained by Dr. Said Mughabghab who sadly passed on during the summer of 2018 after publishing the 2018 edition of the \textit{Atlas}. We are continuing the development of this important compendium. To a large extent, the \textit{Atlas} book is generated from a series of text files given in a single purpose domain-specific format. Therefore we developed a software API and began the systematic assessment of the \textit{Atlas} files. With this work past, we are now focusing on new efforts to expand the quality and scope of the \textit{Atlas}. Current and recently completed projects include a cross comparison of the \textit{Atlas} bibliography with Nuclear Science References and the EXFOR data library, a better determination of average resonance parameters, and using machine learning to assess the correctness of the spin group assignments of resonances tabulated in the \textit{Atlas}.
