Abstract

High-accuracy Multi-Configuration Dirac-Hartree-Fock calculations of ionization energies with Configuration Interaction have been carried out for tungsten ions (W$^{2+}$ to W$^{71+}$) by means of the GRASP code. A comparison with other available experimental and theoretical data, including those calculated by FAC code based on the Dirac-Hartree-Fock-Slater method and with the NIST database has been presented. This work provides a new set of recommended ionization energy values for tungsten ions using state-of-the-art theoretical calculations with uncertainties ranging from 0.07 eV to 0.4 eV, which seems to be a significant improvement over the previous reference uncertainties.
