摘要: 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 3d9414l' and through 3d94l 5l' is emphasized. The trend of DR through 3d94l4l' shows irregularities at relatively low temperature due to the progressive closing of DR channels as atomic number Z increases.
