Photoionisation of Fe XXIII and Fe XXIV is investigated using the R-matrix method, with particular attention being given to photoejection of the K-shell electron. In both cases, good agreement (to within 5 ) is found with earlier calculations of the background cross-section. However, the present work is the first to determine resonance structure just below and above the photoejection threshold energy.
