Dielectronic satellite spectra from hollow He- and Li-like ion states in fluorine

About two decades ago, very unusual highly-resolved x-ray spectra were observed using a femtosecond laserproduced plasma that included a new type of satellite lines identified as being emitted from the autoionizing states of hollow ions (such as, for example, exotic KK hollow ions with the empty K shell). Though atomic structure calculations were able to predict the locations of such newly observed spectral features with reasonable precision, the relatively high intensity of these so-called hypersatellite lines, produced mainly in high-power laser plasmas, is far from being understood. The analysis of previous experiments with Teflon on the Leopard laser performed under different conditions related to laser pulse and contrast revealed the existence of KK hollow fluorine ions and motivated systematic theoretical studies of dielectronic satellite spectra from hollow ion states starting with He- and Li-like fluorine ions presented in this paper.
