摘要：
This paper reviews how atomic physics data are provided and needed in hot dense plasmas produced by the interaction of high-power lasers with solid targets. These plasma are bright X-ray sources localised in space and time and their X-ray emission is studied mainly in the 0.1-3 ke V spectral range by emission and absorption spectroscopy and imaging. Detailed atomic models are required to analyse the experiments and radiative hydrocode simulations need the description of atomic physics in a very wide range of plasma parameters. In this paper, emission spectroscopy is illustrated by the study of the collision of two aluminium plasmas. The example of probing an X-ray laser medium shows the important parameters for absorption spectroscopy. Opacity measurements of X-ray heated samples done by different laboratories mainly in Al, Ge and Fe samples give detailed and Rosseland mean opacities in the XUV range.
