Abstract

Self-consistent relativistic Dirac-Hartree-Fock calculations have been made of some lowlying electronic energies for the atoms of all elements in ground-state ds² electron configurations. The results indicate that, contrary to some previous estimates, the ground electronic state of atomic Lr could be in either the 5f¹⁴6d7s² or the 5f¹⁴7p7s² electron configuration. The separation between the lowest energy level of the 5f¹⁴6d7s² configuration and the lowest energy level of the 5f¹⁴7p7s² configuration is estimated to be (0 \ifmmode±\else\textpm\fi 3) \ifmmode×\else\texttimes\fi 10³ cm^\ensuremath-1 for atomic Lr.
