Investigation of optical spectroscopy in W¹³⁺ ions

This study presents the investigation of magnetic dipole transition lines of W13+ ions in the wavelength range of 200-700 nm at a low-energy electron beam ion trap. Seventeen lines emitted from W13+ ions have been observed with three being reported experimentally for the first time. The atomic structure calculation and spectra simulation of W13+ ions have been carried out using the multiconfiguration Dirac-Hartree-Fock method combined with the relativistic configuration interaction approach and the collisional-radiative model, respectively. The theoretical calculations are in reasonable agreement with the experimental observations, and most of the observed lines have been identified.
