Benchmarking of Hollow Fluorine Ion Modeling with Laser Produced Plasma Experiments*

We continue our studies of exotic ions in dense plasmas with the major focus on KK hollow ions (with a completely empty K shell). Such exotic states manifest through the appearance of uncommon satellite lines (hypersatellites) that were originally observed in femtosecond laser produced plasmas. Since then, hollow ions have been found radiated from other dense plasma sources, but more benchmarking studies are needed to fully understand their relatively high intensities and applications. Here we present atomic data and modeling of radiation from KK hollow fluorine ions and benchmarking of line intensities of such hypersatellites with the experimental results. The experiments with Teflon foils were performed on the Leopard laser at UNR operating in femtosecond regime with different contrast. The major focus was on line radiation from KK hollow states of B- and C-like fluorine ions that produced the most intense hypersatellite spectral features in a spectral region 15.4-16.6 Å (between H- and He-like F fluorine resonance lines).  Future work is discussed.
