Dear Peter, I apologize for late reply - I was travelling with a very limited access to email ... Thank you very much for your clarification. Yes, I understand now, I was really mixing 2 different concepts - the spectrum quality (profile) and the energy of the core levels. If I understand you cor

You are mixing 2 concepts: a) Yes, the final state rule applies and thus for XES calculations you should NOT use a core hole, but use the ground state DOS. b) Strictly speaking, only E-tot is a valid quantity in DFT. In particular, the eigenvalues are in principle NOT excitation energies. How

There is a lot of literature on this. Have you looked at (for instance) the work of Les Allen, as well as the work of the group who wrote the TELNES script? N.B., "electron gun", not "electronic gun". Electronic microscope is an all too common typo. On Fri, Aug 28, 2015 at 10:19 AM, Vladimir Timo
