Information management tools for Evaluated Nuclear Structure Data File (ENSDF) interrogation and dissemination

The evolution of Information Technology has made it possible to provide the Nuclear Data community with various flexible tools customized to respond to individual data queries, to provide visualization, and facilitate dissemination. In another effort to further these developments, the IAEA's Nuclear Data Section has developed a set of applications based on a relational database designed for nuclear structure and decay data. The tools presented in this work mainly use the nuclear structure and decay data obtained from ENSDF and the Nuclear Wallet cards. The present set of applications comprises an interactive Chart of Nuclides (LiveChart) not only presenting the Chart graphically, but also allowing the visualization of data patterns while changing filtering criteria, a web-based query application and a desktop version of the relational database giving support to expert users to customize their data-processing applications. Some examples of the three software tools are presented.
