AN IMPROVED REGULARIZATION TECHNIQUE FOR THE ANALYSIS OF ANOMALOUS SCATTERING DATA

The Tikhonov regularization method is applied in a new iterative way t o extract partial structure factors (PSFs) from anomalous X-ray scatte ring data. Monte Carlo simulations are performed to produce sets of in tensity curves from an amorphous molybdenum-germanium alloy (14 at.% M o), from which the PSFs are then obtained. The role of computer simula tions in the error estimation and in choosing the optimum measuring st rategy to yield sufficiently precise results is discussed.
