TL;DR: In this article, the beryllium atom with basis sets of the type used by Drake and Goldman in calculations on one-electron systems was analyzed and the results showed that the energy converges toward the Dirac-Fock limit monotonically from above.

TL;DR: In this article, a method for obtaining fully relativistic effective core potentials from numerical Dirac-Fock self-consistent field calculations is developed for Ca and T1.
Abstract: A method is developed for obtaining fully relativistic effective core potentials from numerical Dirac-Fock self-consistent-field calculations. Analytical forms for the effective core potentials are derived for Ca and T1, and the results of valence-only Dirac-Fock calculations are presented.
