Portal data pipeline has been automated. Data is fed into the pipeline by physicists. The pipeline then processes the updated data files and automatically generates or updates the related web pages. This allows the portal to scale organically as new elements and data properties are added in upcoming updates.
Data for Mg, Ca, and Sr, with rolling release of new data for other elements.
Hyperfine constants for more states.
Magic wavelengths and magic-zero (tune-out) wavelengths.
More polarizability options.
Version 2.0 (March 2022)
Portal interface redesigned to allow for easy navigation between different properties of the same element.
Energies of Li, Be+, Mg+, Ca+, Rb, Sr+, Ba+, Fr, and Ra+ states not available in NIST ASD database added.
Data for 13 highly charged ions of interest to atomic clock development added.
About the project page updated.
Unit buttons added.
An option to download files in csv format included.
Version 1.0 (April 2021)
Included transition matrix elements, transition rates, radiative lifetimes, branching ratios, polarizabilities, hyperfine constants, and nuclear data for Li, Be+, Na, Mg+, K, Ca+, Rb, Sr+, Cs, Ba+, Fr, and Ra+.
