From ENSDF to NuDat: Search, Filter and Visualize Nuclear Data

The National Nuclear Data Center (NNDC) at Brookhaven National Laboratory (BNL) develops NuDat, a web application where users can explore several databases containing nuclear structure, nuclear decay, and neutron-induced nuclear reaction information. NuDat is the primary web application used to query and visualize nuclear data from the Evaluated Nuclear Structure Data File (ENSDF). ENSDF contains meticulously evaluated recommended values derived from all published experimental nuclear structure and decay data. Over 6 million downloads are made through NuDat each year for research, education, and a wide range of applications. The current technology used within NuDat was first developed over 15 years ago and since then significant improvements to web technologies have been made. Many new features have been implemented for NuDat 3.0 such as additional datasets, customizable color palettes, and a 3D version using Three.js. The 3D chart of nuclides offers an intuitive visualization that provides users with an alternative perspective on nuclear physics phenomena. By modernizing NuDat and continuously integrating new features, the NNDC aims to provide an enhanced user experience that promotes discovery and exploration of nuclear data properties.
