Abstract:
In this paper we report calculations for energy levels and radiative
rates for transitions in Fe IX.
The General purpose Relativistic Atomic Structure Package (GRASP) has
been adopted for the calculation of energy levels and radiative rates.
Energies for the lowest 360 levels, including those from the
(1s22s22p6) 3s23p6, 3s23p53d, 3s3p63d,
3s23p43d2, and 3s23p54l configurations of Fe IX, are
reported. Additionally, radiative rates, oscillator strengths, and
line strengths are reported for all electric dipole (E1), magnetic
dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2)
transitions among these levels. Comparisons are made with the
available results in the literature, and the accuracy of the present
data is assessed.
