The K X-ray line structures for a warm dense copper plasma

Ionization affects the energy and shape of the characteristic X-ray lines that may be excited by energetic electrons in a partially ionized plasma. We present the first theoretical predictions for copper K-line spectra in different ionization states, one of a systematic series of computations on how ionization affects inner-shell X-ray lines. Detailed computations such as these may make it possible to use individual hard X-rays lines as diagnostics for warm, dense plasmas when high-resolution X-ray spectra are available.
