Transmission measurement of photo-absorption cross section of aluminum in soft X-ray region of 50 to 250 eV
The photo-absorption cross section of aluminum was obtained from the ratio of transmission of aluminum thin-films with different area densities from 50 to 250 eV with synchrotron radiation monochromatic beam.Two samples with different area densities were used to minimize the uncertainty caused by the sample surface oxidation and systematic factors of the X-ray source,beamline,and detector.The experimental results are in good agreement with the published data and FEFF program calculations in general.
