摘要：

The excellent performances of our 35-element Silicon Drift Diode detector over a very wide energy range (>= 0.5 keV), allowed us to investigate the existence of magnetic circular dichroism in X-ray fluorescence cascade processes. We report the results of a test experiment performed at the Tb L-III-edge using an amorphous TbCo2 thin film which was magnetically saturated with an external magnetic field of 0.5 T. In a single energy scan, two XMCD spectra were obtained by monitoring separately the integrated intensities of L-alpha and M-beta emission lines of the Tb atoms.
