Abstract

X-ray line emission originating from hollow ions has been identified in dense laser-produced plasmas by means of two-dimensional X-ray optics and spectral simulations performed by the code MARIA. It is shown that for plasma coupling parameters > 1 excited states correlation effects of hollow ion configurations exceed the usual ground-state population channel by many orders of magnitude. The intensity of the emission of these excited-state hollow ions can be stronger than those of the usual satellite or resonance line transitions and lead to a remarkable distortion of the spectral emission. Detailed spectral simulations for the K-shell spectral interval are carried out for the 1s21nl′-Rydberg configurations as well as the K1L0M1N1, K1L0M1N0O1, Science Ltd. All rights reserved.
