Abstract:
In this paper we report on calculations for energy levels, radiative
rates, collision strengths, and effective collision strengths for
transitions among the lowest 25 levels of the n≤5 configurations
of H-like Fe XXVI.
The General purpose relativistic atomic structure package (GRASP) and
Dirac atomic R-matrix code (DARC) have been adopted for the calculations.
