We present complete spectroscopic data and a detailed theoretical investigation of C-like W (WLXIX) based on the fully relativistic multi-configuration Dirac–Fock (MCDF) method. We included quantum electrodynamics (QED) corrections due to vacuum polarization, and self-energy effects and Breit correction due to the exchange of virtual photons between two electrons are fully considered in our calculations. For the lowest 205 fine structure levels, we have provided the energy levels and radiative data for multiple transitions such as electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1), and magnetic quadrupole (M2) and identified soft X-ray transitions (SXR) and hard X-ray (HXR) transitions from highly excited states to ground state have been predicted. The credibility and authenticity of our furnished results and related calculations have also been performed using another independent fully relativistic configuration interaction program (Flexible Atomic Code) based on self-consistent Dirac–Fock–Slater iteration method. A reasonably good agreement is found between our two independent atomic structure calculations. We also compared our computed energies with experimental energy levels compiled by NIST and other available theoretical data in the literature, and there are a few minor differences discussed. We have studied the intensity spectra for transitions decaying to ground state for W LXIX. We expect that our newly reported atomic and radiative data of C-like W will help identify and analyze spectral lines obtained from various diagnoses of solar, fusion plasma research and astrophysical exploration.
