Notes. These lifetimes only include contributions from single-photon transitions. The lowest 31 levels arising from the 1snl(n ≤ 4) configurations in Ne IX are shown here. The full table is 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.

Initial download of the metrics may take a while.
