We measured the dielectronic recombination satellites and resonant= excitation contributions to the $3\rightarrow 2$ line emission of= Lithium-like iron. At electron energies just above the excitation= thresholds, distorted wave approximation underestimates the excitation= cross sections due to the lack of resonant effects. Recent R-matrix= calculations are in good agreement with our measurements.
