Notes.ERCI are energies that include low-frequency Breit, vacuum polarization, and self-energy corrections from present calculations, EMR−MP energies from Vilkas & Ishikawa (2004a), ENIST observed energies from the NIST database (NIST Atomic Spectra Database 2013), EDZ1 and EDZ2 observed energies from Del Zanna (2011) and Del Zanna et al. (2014), respectively. The notation from the NIST database has been retained and values in square brackets means that the values were obtained from interpolation. Energies from the NIST database followed by ? are classified as uncertain. Tables for all ions are available at the CDS.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
