“…5 by the appearance of C, Na and K signal at m/q = 12, 23 and 39 respectively and an accumulation between m/q = 2 and 3 of what likely is highly charged ions accelerated by plasma effects. Significant X-ray driven acceleration of light ions has been observed from solid density samples [18] earlier and was used for an accurate determination of the beam focused beyond the Rayleigh length [19].…”

“…The plasma induced by XUV/SXR pulses is mainly generated as a consequence of the photoeffect (electron-hole or excitonic "plasma") and in less proportion by the collisional absorption, i.e., inverse Bremsstrahlung. 96 Emission spectra from plasmas produced by short 97 as well as ultra-short 98,99 pulses of shortwavelength lasers have been explored in not so many studies. Peculiar observations have been reported, which require more extensive studies in the future.…”

“…Mass spectra have also been taken from solid targets ablated by focused XUV and SXR from free-electron lasers. 66,97 Li et al 102 took advantage of the synchrotron VUV tunability to characterize combustion intermediates in premixed ames and those from other systems in combustion research, such as hydrocarbon ames, diffusion ames, plasma and catalytic reactions. Giuliani and colleagues 103,104 studied the application of synchrotron radiation for the photoactivation of ions in the short wavelength region, which is a rapidly growing eld.…”

“…In our previous studies on XFEL-matter interactions [9][10][11][12][13][14] we have used the Cretin software to perform NLTE calculations. The NLTE model was originally developed for low-density warm matter, using a so-called plasma formulation, which is appropriate for samples exposed to high-fluence photon pulses, where the average ionization of the system is high and chemical bonds are of negligible significance.…”
