J/A+AS/116/573 J/A+AS/116/573 Transitions for FeIII P Quinet Astron. Astrophys. Suppl. Ser. 116 573 1996 1996A&AS..116..573Q Atomic physics atomic data Fe III radiative transition probabilities Radiative transition probabilities have been calculated for states within the 3d6 configuration of Fe III. Magnetic dipole (M1) and electric quadrupole (E2) transition probabilities have been obtained using average energies, electrostatic and spin-orbit integrals adjusted so as to fit the observed energy levels. The most important configuration interaction (CI) and relativistic effects were included explicitly in the calculations, using the relativistic Hartree-Fock (HFR) method due to Cowan. The present work represents a refinement of previous monoconfigurational calculations of transition probabilities for forbidden lines of astrophysical interest in Fe III.
