Abstract

By means of high spectral and spatial resolution x-ray spectroscopic methods we have observed for the first time simultaneously two-electron and higher-order intercombination transitions from autoionizing levels in large scale optically thick laser produced plasmas. Intercombination transitions as well as the two-electron op-satellite transitions in Li-like ions have anomalous large intensities (up to a factor of 14). Sophisticated non-Maxwellian opacity simulations treating extended configuration interaction atomic data employing the MARIA-code reveal, however, good agreement among forbidden transitions.
