X-ray reemission from gold disk targets heated by soft x-ray radiation

X-ray reemission from gold disk targets,which were heated by intense soft X-ray radiation((2—6)×1012W·cm-2),had been observed with two time-related soft X-ray spectrometers-The spectra of X-ray reemission were “softer” than those of irradiating X-ray-Temporal evolution of the X-ray reemission was analyzed in terms of a time-modified self-similar solution for the ablative heat wave-
