Description
Dielectronic-recombination (DR) spectra of highly-charged W$^{𝑞+}$ and
Ir$^{𝑞+}$ ions have been measured by employing the Electron-Beam Ion
Trap (EBIT) at National Institute of standards and Technology [1]
and the Main Magnetic Focus Ion Trap (MaMFIT) [2] at Justus-Liebig
Universität Gießen, respectively, over wide ranges of electron-beam
energies. A series of DR resonances involving transitions between 2𝑙 →
3𝑙′ and 2𝑙 → 4𝑙′ subshells in Na-like through Ar-like tungsten have
been revealed in the NIST EBIT spectra, while in the MaMFIT, DR
resonances involving transitions between 2𝑙 → 3𝑙′ subshells in K-like
through Ni-like iridium were seen. Detailed modeling of the observed
spectra has been performed.
