Benchmarking calculations of excitation energies and transition properties with spectroscopic accuracy of highly charged ions used for the fusion plasma and astrophysical plasma

In this work, we mainly focus on reviewing our two projects performed in the past decade. One is about the ions with ≲ 30 that are generally of astrophysical interest, and another one is about the highly charged krypton ( = 36) and tungsten ( = 74) ions that are relevant in research of magnetic confinement fusion.

Two different and independent methods, namely, multiconfiguration Dirac-Hartree-Fock (MCDHF) and the relativistic many-body perturbation theory (RMBPT) are usually used in our studies. As a complement/extension to our previous works for highly charged tungsten ions with open M-shell and open N-shell, we also mainly focus on present and discuss our complete RMBPT and MCDHF calculations for the excitation energies, wavelengths, electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2) transition properties, and level lifetimes for the lowest 148 levels belonging to the 33 configurations in Al-likeW61+.
