Dielectronic recombination of Ni-, Cu-, and Zn-like tungsten ions

•We have calculated dielectronic recombination for Wq+(q=46−44) using flexible atomic code.•Effect of configuration mixing has been investigated.•Total rate coefficients are compared with other available predictions in detail.

Dielectronic recombination (DR) for Ni- and Zn-like Wq+ (q=46, 44) has been investigated extending the previous theoretical methodology (Kwon and Lee, 2016 [6]) applied for Cu-like W45+ which treats configuration mixing (CM) between resonances, non-resonant stabilization to non-closed inner-shells and decays to autoionizing levels possibly followed by cascades. For W46+ DR via 3[s,p,d]174lnl′ and 3[s,p,d]175lnl′ resonances (Δnc=1, 2) are included to the total Maxwellian rate coefficient. CM between 3p63d94lnl′ and 3p53d104lnl′ resonances largely changes low energy DR near the threshold. For W45+ radiative decay channels 3d104l′n′l′′ (4
