Dear Stefaan Sir, Thank you for your reply. But is your reply indicating that.......
the excited states *may be* those states having higher energy....but it is *not sure* that whether the states having higher energy will be the excited states of the system??......Please assure me that this is the meaning of your reply...........but if this is the meaning then another question is that may it be happened that some converged solutions of the system actually never be found in reality??...if this is true then the question is why?..........Please forgive me to ask so many questions at a time. with best regards, Shamik Chakrabarti On Thu, May 6, 2010 at 3:57 PM, Stefaan Cottenier < Stefaan.Cottenier at ugent.be> wrote: > > I have a basic question regarding DFT.
