Abstract:
We tabulate theoretical line strengths, f-values and transition
energies for the beryllium-like ion Fe XXIII. Transitions are between
levels 2l12l2S'L'J' and 2l3nl4SLJ with n = 2, 3, 4. The
calculation uses the well known configuration interaction program CIV3
in which relativistic effects are allowed for by means of the
Breit-Pauli approximation. We give a detailed comparison of our
oscillator strengths with those which Chen & Ong (1998, Phys. Rev. A,
58, 1070) obtained using the relativistic Dirac code GRASP2.
