The absorption of soft X-rays by gold at density of 
and
temperature of
has been measured in the photon energy range of 50 to 300 eV. For that
purpose, a thin gold foil tamped by carbon was heated by thermal X-rays
generated in a laser-irradiated gold cavity and probed by X-rays
emitted by a synchronized tungsten backlighter source. The measured
absorption was compared with numerical calculations based on the
super-transition-array model.
