Analytic Hartree-Fock calculations have been carried out for the lowest neutral atom 3d^n-24s^2 states of Ti through Zn. Except for Cr and Cu, these calculations are for the neutral atom ground states. The results are compared with the earlier 3d^n state calculations. It is observed that the 4s electrons have little effect on the 3d and inner shells.
