Community Portal for High-Precision Atomic Physics Data and Computation

This project aims to bridge the gap between the development of atomic physics research codes and the need for data and software by the user community. To meet the needs of the community, we (1) continue to develop a scalable and sustainable online data portal with an automated interface for easy update and addition of new data, and (2) continue the development of open-access atomic software based on our research codes that allow generating large volumes of data with automated accuracy assessments. The portal provides energies, wavelengths, transition matrix elements and rates for various transition types, branching ratios, lifetimes, polarizabilities, hyperfine constants, and other data. We plan to make data for over 100 atoms and ions, including high-charged ions, available for the user community by the end of this project. Building on a prototype developed in an initial project, the new portal will significantly advance scalability and sustainability. The present version of the portal is available at udel.edu/atom.
