Hi Pinit, here is what you can expect from a SDD: "At X-ray energies greater than silicon K absorption edge, which we have measured for crystalline silicon to be 1839 eV, the response function of the device shows two distinct peaks in addition to the primary one. One of them at energy

I have an SDD and find very little strength in the escape peak or the Si Ka peak. I have seen Si from the sample. I can't speak to how well Si XAS works because my beamline doesn't go down that far. mam On 2/9/2016 10:25 AM, Pierre Lecante wrote: Hi Pinit, here is what you can

[Ifeffit] Feature near edge of Ni XANES spectrum

2016-02-09 Thread Aditya Shivprasad
Dear list, I have obtained nickel XANES spectra (attached) from metallic Zircaloy-2 nuclear fuel cladding (Zr, 1.5% Sn, 0.15% Fe, 0.1% Cr, 0.05% Ni). In the spectrum, I identify the edge as being approximately 8331-8332 eV (based on maximum of first derivative), as it is for pure Ni. However, I

Hello Aditya, If I understand correctly, the nomenclature you are using is a little misleading. The sharp feature that you are referring to is a rising-edge feature and is not after the edge. The is a classic feature for square planar complexes and Ni does form a lot of those. The origin of this
