Laboratory measurements of resonant contributions to Fe XXIV line emission

Using an electron beam ion trap, we have measured the relative cross sectio ns for Fe XXIV line emission at electron energies between 0.7 and 3.0 keV. Good agreements with distorted wave and R-matrix calculations are found at energies above 1.5 keV. At lower energies, the contributions of resonant ex citation are observed and agree with R-matrix calculations. Below the excit ation thresholds, the intensities of dielectronic recombination satellites for capture into n greater than or equal to 5 levels are measured.
