Abstract The transition energies of the 1ss S 1sp P transitions in Li-like Th ions were calculated by combining the multi-configuration Dirac-Hartree-Fock (MCDHF) method with the model-quantum electrodynamics (model-QED) approach. The effects of electron correlation, Breit interaction, and QED effects were analyzed in detail. The isotope shifts, including the mass shifts and field shifts, due to the 2s S 2p P transitions were then calculated using two different methods, namely, the MCDHF method and the finite-field method. The results show that these two methods are in excellent agreement.

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.
