X-ray spectrum of a laser-produced iron plasma

We present the analysis of the x-ray spectrum between 9.5 and 17.0 {} of a laser-produced iron plasma. Wavelengths and relative intensities for 96 lines are measured. For the strongest part of the spectrum, above 13 {}, almost all of the observed lines are identified as radiation from FeXVII, FeXVIII, and FeXIX ions. Measurements were made with a curved-crystal spectrograph. Calculations were full intermediate coupling, Hartree-Fock with relativistic corrections. Coulomb-approximation oscillator strengths were used to help in the line identification.
