Abstract
The calculations of Badnell et al. [Phys. Rev. A 48, R2519 (1993)] demonstrated an apparent breakdown on the isolated-resonance approximation within certain resonant contributions to the 3${\mathit{s}}^{2}$ $^{1}$S\ensuremath{\rightarrow}3s3p $^{3}$P transition in ${\mathrm{Fe}}^{14+}$. We have now carried out detailed analyses of selected resonant structures for this transition. Comparing calculations using the independent-processes and isolated-resonance approximation, interacting resonance theory, and the R-matrix close-coupling method, we determine the nature of the interactions between resonances and demonstrate the sensitivity of the size of the resonant contribution to the positions of the resonances.
