Hello all!

I am generating a PP for Lanthanum in the ground state.  The cross excitation 
energies are way off between the AE and PT series.  Can anyone provide advice 
to fix this?  I've tried incorporating core corection, but I don't seem to be 
able to choose "good" core radii, since I am not getting anything which is 
bringing me close to where my excitation energies should be (the AE values).  
I've read Louie, Froyen, Cohen, Phys. Rev. B 26, 1738 (1982), but it hasn't 
helped.

I've tried including the 5p states as semicore, but this makes things much 
worse.  Note that in this configuration I cannot incorporate 5s states as 
redundant L channels with different n values are not allowed.

Any advice is greatly appreciated!
