Abstract
We have designed a web portal that is able to provide the scientific community with easily accessible high-quality atomic transition data. The application codes used for the portal are capable of calculating a very broad range of atomic properties to answer the significant needs of atomic, plasma, and astrophysics communities. ☐ There is a demonstrated need for high-quality atomic data and software in several scientific communities, from studies of fundamental interactions to development of future technologies. In a number of present research fields-including studies of fundamental interactions, atomic clock research, analysis of astrophysical data, plasma science, studies of quantum degenerate gases, quantum information, and more-accurate atomic theory is indispensable to the design and interpretation of experiments, with direct experimental measurement of relevant parameters being impossible or infeasible. Accurate theory is also useful is comparing to the results of new experiments. Further rapid advances in applications involving complex atoms will require accurate knowledge of basic atomic properties, most of which remain highly uncertain and difficult to measure experimentally. Moreover, the search for further applications of rich, complex atomic structures is hindered by the lack of a reliable theoretical framework. This research aims to solve this problem by developing general community code and open access to data, easily reachable through a community web portal. These new cyberinfrastructure elements will advance our understanding of complex atoms and provide a wide variety of data, where the methodology and codes were already developed. ☐ We have specifically designed the site to allow users to quickly obtain most commonly requested types of data with minimal user interaction: all data is available within a few button clicks from the home page. The data is verified through multiple methods of calculation, and can be downloaded with uncertainty values. Version 1 of the portal, providing access to several transition properties for twelve elements, is available for public use at http://www.udel.edu/atom. In the future we will use community input to improve the design and functionality of the site, while adding data for many more atoms and ions.
