Abstract This paper analyses the effect of configuration complex on dielectronic recombination (DR) process in highly ionized plasmas (Xe26+, Dy38+, W46+) by using the multiconfiguration relativistic Hartree--Fock method. Resonant and nonresonant radiative stabilizing transitions and decays to autoionizing levels followed by radiative cascades are included. Collisional transitions following electron capture are neglected. The remarkable difference between the isoelectronic trend of the rate coefficients for DR through 3d94l'4l' and through 3d94l'5l'' is emphasized. The trend of DR through 3d94l'4l'' shows irregularities at relatively low temperature due to the progressive closing of DR channels as atomic number Z increases.

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.
