New excitation channels for satellite transitions in non-stationary dense plasmas

Abstract

New excitation channels for the explanation of the strong emission of Li-like and Be-like satellite transitions in numerous picosecond and subpicosecond laser-produced plasma experiments are proposed. `Blue Li-like satellites' of the He-like resonance line W are predicted. Corresponding spectral simulations exploiting new calculated atomic data for these mechanisms are in rather good agreement with experimental single-shot spectra of plasma produced at the intensities up to and recorded by means of a high-resolution spherically bent mica crystal technique.
