      abstract     = {A frame store pn-junction CCD (pnCCD) detector was applied
                      to study thermally induced interdiffusion in Fe/Pt thin film
                      multilayers (MLs) in a temperature range between 300 and 585
                      K. Based on the energy resolution of the detector the
                      reflectivity was measured simultaneously in a spectral range
                      between 8 keV < E < 20 keV including the Pt L-edge energies
                      close to 11.5 keV. Above T - 533K we find a strong drop of
                      intensities at 1st and 2nd order ML Bragg peak interpreted
                      mutual interdiffusion. Considering a simulated model of
                      interdiffusion it has been found that the concentration of
                      iron that diffuses into the platinum sub layers is higher
                      than that of platinum into iron. The time dependence of
                      inter diffusion was also calculated in the range of 533-568K
                      and was described by the Arrhenius equation D(T) - D-0
                      exp(-H-a/k(B)T). The activation energy for the MLs used [Fe
                      1.7 nm/Pt 2 nm](50) was found to be 0.94 +/- 0.22 eV. (C)
