Hi, I have a question concerning the RMULTIPLIER-Card in XANES-Calculations. I made some calculations with different rmult values (1.00, 1.01, 1.05, 1.10) and found a shift of the absorption-edge or rather the slope of the peak. I attached the diagram of this calculation (Sulfur-K-edge of gypsum). My question is, what could be a physical reason for this behaviour? With this Parameter one change the interatomic disctances. Hence the interference phenomena and the curve progression should be change, too. Is this right? Thanks for your help. Have a nice day, Eckhard PS: the same behaviour occurs in a inverse sense for rmult < 1 --------------------------------- Eckhard Bosman e.bosman@stud.uni-goettingen.de +49 (0)551-39-14441 Raum: E0.104 Institut für Röntgenphysik Friedrich-Hund-Platz 1 37077 Göttingen Germany
