 I kindly ask for indications on setting up core-level photoemission calculations. In the example file about 2p core-level photoemission from NiO including ligand field effects, the energy balance for the final states is reported as :  I kindly ask for indications on setting up core-level photoemission calculations.

-My question: is this treatment correct for cPES or, since the 2p electron is photoemitted rather than promoted in the d states as for XAS, I have to reduce the final state occupation of the d states by one electron (e.g. 2p^5 L^10 d^n, 2p^5 L^9 d^n+1, etc...)? +My question: is this treatment correct for cPES or, since the $2pelectron is photoemitted rather than promoted in the $dstates as for XAS, I have to reduce the final state occupation of the $dstates by one electron (e.g. $2p^5 L^{10d^n$$2p^5 L^9 d^{n+1}$, etc...)? 
  
 Thanks a lot in advance. Thanks a lot in advance.
