The ground state of the germanium atom is a P configuration which can be described by a single determinant. The orbitals for the determinant were obtained from a LSDA calculation for the atomic ground state. A spherically-symmetric function was used for both up- and down-spin electrons of the form of the function f of Eq.() with =10 . It is appropriate to choose this form for a pseudo-atom because the lack of electron-ion cusp condition implies that should be smooth at the origin. For the u functions we used the same form as for the HEG and germanium solid calculations, Eqs.(-), with =10 .
