[Pw_forum] About atomic states.

[robert.guzman]

Dear's QE users
I have a question about the calculation of atomic states with DFT. I 
don't understand the spherical aproximation of density when the atomic 
levels are partially filled. I looked the "Notes on pseudopotential 
generation (Paolo Giannozzi)", Martin book's, and Kohanoff book's, but 
did not found the explanation of this aproximation. Someone could help 
me with an explanation or a reference.

On other hand I built my pseudopotential using the ld1.x code but I 
don't know how this code work. Please someone could give me this 
information with a reference or a explanation.

Best Regards.
