Re: [Ifeffit] Self-Absorption Corrections

hi all, Here is a gif of Nb2O5 at Nb K-edge and TiO2 at Ti K-edge. Both collected withb same geometry and detectors and same BL (SSRL 11-2). Fluo was collected at 90° to the beam (while transmission data was collected on the exact same sample). both spectra are normalized. Is there not any remaining self-absorption in the fluo spectrum for Nb2O5, despite data collected at 90° ?? (while TiO2 sounds fine, as Troeger predicted ?). thank for your expertise ! -- Francois FARGES Laboratoire des Géomatériaux Université de Marne la Vallée 5 Bd Descartes-Champs S/Marne 77454 Marne la Vallée cedex 2 TEL: 01 49 32 90 57 from outside France: +33 1 49 32 90 57 FAX: 01 49 32 91 37 from outside France: +33 1 49 32 91 37
