Notes. From left to right, we list the atom species, transition wavelength, the dominant configuration and term designation for the lower and upper levels, the energy of the lower level, the series limit energy for that level, the energy of the upper level, the series limit energy for that level, the orbital angular momentum quantum numbers of the optical electron in the lower and upper levels, the total angular momentum quantum numbers of the lower and upper levels, and finally the calculated line broadening cross-section σ due to hydrogen atom impact at a collision velocity of 104 m s−1 and corresponding velocity dependence parameter α. The units for the wavelength are Å, the energy is listed in cm−1, and atomic units for the cross-section σ, respectively. The velocity parameter α is dimensionless.

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.
