Abstract Based on the multi-configuration Dirac--Fock method, this paper has made theoretical calculations for the dielectronic recombination cross-sections and the high-$n$ dielectronic satellites to K$\alpha$ resonance line in helium-like aluminium ions. It is found that high-$n$ dielectronic satellites are seriously mixed with resonance line, which leads to a significant increase in both the apparent width and the intensity of K$\alpha$ resonance line. They also induce a positional shift of K$\alpha$ resonance line.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
