We tabulate theoretical line strengths, f-values and transition energies for the beryllium-like ion Fe xxiii. Transitions are between levels and with . 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 ([CITE]) obtained using the relativistic Dirac code GRASP2.
