Abstract Excitation energies, transition wavelengths and probabilities of the 2p6, 2p5 3l, 2s 2p6 3l (l = 0; 1; 2) states along the Ne-like isoelectronic sequence from Z =21-92 have been calculated by using the Multi-configuration Dirac-Fock package GRASP92 and a newly developing radiative transition program REOS99. In the calculations, the correlation and relaxation effects are included systematically.Based on the calculations, all possible energy crossings among the level groups with the same parity and total angle momentum have been presented. It is found that there are strong conˉguration interactions in some particular Z regions with energy-crossings, and which can cause a dramatic change of the related transition probabilities.

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.
