“…Plasma radiation is dispersed by a gold coated spherical reflection grating (1200 lines/mm). The absolute number of VUV photons is estimated to be of the order of 10 8 photons per pulse, corresponding to 10 9 photons per second at 10 Hz operation of the lasers, which is similar to previous work [24,25,[42][43][44]. The typical bandwidth of the dispersed VUV photons is set to ∆λ ≈ 2.4 -5.9Å, depending on the spectral features to be resolved in the respective energy regime.…”

“…The experimental setup has been described in detail elsewhere [40]. Briefly, the experimental setup consists essentially of the following components:…”

“…The typical bandwidth of the dispersed VUV photons is set to ∆λ ≈ 2.4 -5.9Å, depending on the spectral features to be resolved in the respective energy regime. Calibration of the VUV source and its photon energy scale is performed by taking ion yields of molecular oxygen [40,45]. The well-known vibrationally resolved transitions in the energy range between 12.19 and 13.78 eV are used for this purpose [46].…”

“…The present paper uses a technique that was applied to photoionization and autoionization of atomic singlet oxygen O( 1 D) previously [24,25]. Suitable photochemical precursors of electronically excited atomic or molecular species are photolyzed using a pulsed, tunable laser.…”

Single-photon photoionization of oxygen-like Ne III

“…In a calculation that included core excited states, Nahar [23] obtained the PI cross-section of the isonuclear series O I to O VII using an ab-initio R-matrix method. Flesh and collaborators [24] investigated the laser-induced, singlephoton ionization of excited 1 D 2 state of O I; they found Rydberg series' below the ground state of O II. Tayal [25] calculated the single-photon PI cross section for the ground state O I using an R-matrix method.…”
