Abstract: 
Employing the dual laser plasma technique, we measured the extreme ultraviolet (EUV) photoabsorption spectrum of F 2+ ions, spanning the energy range from 53 to 93 eV with an energy resolution ( E / AE ) of 866. The measured spectrum is carefully analyzed by comparing with the available reference data and theoretical calculation using the Cowan code. We identify prominent transitions to the Rydberg series 2 s 2 2 p 2 ns / nd and 2 s 2 p 3 np from the ground level and remarkable transitions to the 2 s 2 2 p 2 ( 1 D ) nd 2 D states from the 2 s 2 2 p 32 D metastable level. Transition energies and line profile parameters are determined by fitting the identified absorption features. The calibration of the spectrometer with well-known transitions allows us to provide line positions for well -resolved resonances with an uncertainty of 20 meV. The reported experimental data of F 2+ significantly contribute to the fundamental atomic database, offering valuable benchmarks for theoretical calculations with potential applications in astrophysics and plasma sciences.
