Quantum optics and atomic interactions

Quantitative comparisons between observed and theoretical wavelengths and intensity ratios are made to confirm the identification of some emission lines observed in the spectra of Na- and Mg-like ions as electric quadrupole (E2) transitions. The transition rates of these lines connecting D symmetry levels and the ground level are calculated using the multi-configuration Hartree-Fock (MCHF) wavefunctions.
