Shift of a recombination discontinuity in the spectrum of x-ray radiation emitted by a laser target

A shift of the Si⁺¹³ + e^–→Si⁺¹² + hν recombination discontinuity was recorded in the emission spectra of glass shell targets: this shift was Δε = 100 ± 20 eV corresponding to a plasma density 1–3 g/cm³. The experimental results were compared with numerical gasdynamic calculations
