LiF crystal block (Korth Kristalle, Germany) grown from the melt in an inert atmosphere
were mechanically cleaved in ambient atmosphere along a (100) plane to obtain platelets of
~1.0 cm2 area and ~0.5 mm thickness. The fresh cleaved samples were irradiated at normal
incidence to isotope-pure highly charged (129XeQ+) ions of diff erent charge states ranged from
Q = 15 to Q = 36, which corresponds to a wide range of potential energies between p E =
2.2 keV and p E =37.8 keV. The ions were extracted from the electron beam ion trap (EBIT)
facility (located at the Ion Beam Center of the Helmholtz-Zentrum Dresden-Rossendorf).
