摘要：
We have been measuring the L-shell x-ray emission produced by dielectronic recombination of neonlike Fe16+ ions populating doubly excitated levels of the form 1s(2)2l(7)3ln'l' in Fe15+. The measurements are carried out at the Livermore electron beam ion trap facility, where we isolate dielectronic resonances by choice of the electron beam energy. We utilize crystal spectrometers to record the x-ray lines generated in the radiative deexcitation of the 1s(2)2l(7)3ln'l' upper levels. The measurements aim to support the identification of such lines in low-density astrophysical plasmas.
