Abstract：
Photoabsorption cross sections at the Al and Fe L_2,3 edges on thin films have been measured at the Beijing Synchrotron Radiation Facility (BSRF) using monochromatic soft X-ray radiation. The measured Fe and Al cross sections are in good agreement with theoretical predictions for energy below the edge, while a poor agreement is observed near the edge region probably because the independent atom approximation is not suitable for photon energy near the absorption edge. Experimental data have been also compared with previous data available in the literature. This work demonstrates that cross section determinations of thin films of low Z atoms in the transmission mode are difficult but are feasible and can be substantially improved using synchrotron radiation.
