Portal for High-Precision Atomic Data and Computation*

We are reporting a release of the Version 1 of the online atomic portal for high-precision atomic data and computation. This portal provides transition matrix elements, transition rates, radiative lifetimes, branching ratios, hyperfine constants, quadrupole moments, and scalar and dynamic polarizabilities for atoms and ions. Version 1 includes data for Li, Be+, Na, Mg+, K, Ca+, Rb, Sr+, Cs, Ba+, Fr, and Ra+. The atomic properties are calculated using a high-precision state-of-the-art linearized coupled-cluster method. All values include estimated uncertainties. Experimental values are included with references where high-precision data are available. Data for more systems will be added in the future, with alkaline earth metal atoms planned for the next release. Future updates will also include releases of user-friendly atomic codes. We seek community input to improve the portal and guide the next stages of the project.
