Abstract We have calculated the forbidden transition energies and magnetic dipole transition probabilities of 2s22p4(3P1－3P2) and 2s22p4 (3P0－3P1) of oxygen-like isoelectronic sequences (Z=10－32) by a method of polarization potential correction. The transition energies show good agreement with experiment and are much better than the calculations in the literature. These results also illustrate that it is feasible to use the dipole expansion of the polarization potential to deal with some dynamic and non-dynamic effects in the central field approach. The relation of polarizability and cut-off radius with atomic number is discussed. We also give the fitted formula between the polarizability $\alpha_1$ and atomic number Z as $\alpha_1$ = 0.73429-9.56644×10-4Z+7.43016×10-5Z2-2.53298×10-6Z3+2.08306×10-8Z4.

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.
