Re: [Wien] core-hole calculation in a molecule

This is certainly interesting. For a molecule an alternative is to remove one electron and then use E-tot(N) - E_tot(N-1) as binding energy. However, in this case due to the charged cells, I'd expect quite some dependency on the cell size and some correction might be necessary. Your findings

Good morning -   Maybe I can give a little help.   I never tried a core-electron binding energy.  Long ago, with the old Univ. Florida APW (NOT LAPW!) code, Asok Ray, Joe Worth, and I did try the Slater transition state for optical transitions in rare gas crystals.  We implemented it in a perio

Dear Wien2k mailing list, I'm trying to calculate core electron binding energies using the Slaters transition state approach (half electron removed from the core compensated by the background charge) in an organic molecule. As part of the usual convergence checking I did four calculations with di

Maybe. You can always check the output of x nn(case.outputnn), where the distances between atoms are listed. Compare it with literature values. PS: First of all you should make the structure without replacing an impurity. This structure can be compared with experimental distances, and
