Abstract

Recent measurements of the absorption coefficients of L transitions in iron and nickel hot plasmas are reported following a brief review of the published experiments on opacities and absorption coefficients which have been performed until now in laser-heated cavities and Z-pinches. Emphasis is put on the impact of these measurements in astrophysics.
