The widely used Roothaan-Hartree-Fock wavefunctions of Clementi and Roetti (1974) for the cations from Li+ through Xe+, and the anions from H- through 1- are improved by reoptimization of the exponents of the Slater-type basis functions. Energy improvements of a few mHartree are found for all ions with Z<or=37. An apparent error in the original Tc- computation is found; the reoptimized energy is 1.8 Hartree lower in this case.
