Single uranium atom simulation using SARC-ZORA basis


Just Got Here
Hi,

I'm doing dft simulating on single uranium atom using spherical SARC-ZORA basis, and want to extract the 7 Kohn-Sham orbitals with pure f component.
Part of input is written below:



geometry
U 0.000000 0.000000 0.000000
symmetry oh
end

charge +6

basis spherical
U library SARC-ZORA
end

relativistic
 ZORA
end

dft
 xc rpbe cpbe96
iterations 300
grid fine
mult 1
end

task dft



After extracting information from u.movecs, I can recover the matrix with 159 rows as Kohn-Sham orbitals and 159 columns as basis functions, and identify 7 degenerate Kohn-Sham orbitals near HOMO/LUMO with high f basis function components. Why do those 7 Kohn-Sham orbitals have contribution from basis function other than f basis function ???
I think they should have only f basis function components.
