I was wondering if anyone had experience in calculating XANES spectra using Feff for the spinel system. The material I was trying to investigate was ZnFe2O4. There were reports in literature that gave satisfying simulation results by Feff so I tried to follow. The feature peaks' positions from my simulation is generally right, but the intensity is definitely wrong. So I guess either someone can give me some suggestion about the getting the intensity right or share with me about his or her spinel XANES calculation experience. My background is mainly in chemistry and material science with general ideas about electronic structure. Any comment or suggestion will be greatly appreciated. Thanks!
