Abstract:
A large-scale configuration interaction (CI) calculation using Program
CIV3 of Hibbert is performed for the lowest 87 fine-structure levels
of argon-like iron ions. We have calculated energy levels, oscillator
strengths, and transition probabilities for all
electric-dipole-allowed and intercombination transitions between the
levels of 3s23p6, 3s23p53d, 3s3p63d, 3s23p54s,
3s23p54p, 3s23p54d, 3s3p64s, 3s23p54f, 3s3p64p,
3s23p55s, 3s23p55p, and 3s23p55d states of Fe ix in the
LSJ coupling scheme. Lifetimes of the 3d levels are also determined.
The calculations include the major correlation effects.
