TL;DR: In this article, the effect of replacing the point model of the atomic nucleus by a nucleus of finite size was explored in relativistic Dirac-Fock calculations on O 7+ and Hg 79+ and it was shown that smaller basis expansions are required for the heavier nucleus in the finite-nucleus model.

TL;DR: In this article, it was shown that the balanced basis expansion of the Drake-Goldman type to 2P 1 2 fails to reproduce the nodal structure although the expansion gives the exact 2p 1 2 2 energy at a single minimum.
