Notes. Column 3 shows the relative intensities (photons) I = NjAji/Ne of the strongest lines, relative to the main transition. The intensities were calculated at an electron density of 109 cm-3 and log T [K] = 6.25, the temperature of peak ion abundance in equilibrium. Values in brackets are those calculated with the CHIANTI database. Columns 4 and 5 show the gf and A values calculated in this work with TECs. The λexp (Å) are our experimental wavelengths (in vacuum), while the λth (Å) values are our theoretical values obtained with the TECs. A “T” in the last column indicates a tentative new experimental wavelength.

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.
