Notes. The experimental level energies Eexp (in Rydbergs, from Del Zanna 2010) are shown, together with those obtained from our scattering target Et and those from the previous scattering calculation (D10). Values in parentheses indicate differences with Eexp. Only a selection of levels is shown.
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.
