Abstract
This paper presents all the leading contributions to the relativistic total energies and ionization
potentials of the ground state of lithium-like ions with a nuclear charge in the range Z = 3 − 20.
Correlation, relativistic and quantum-electrodynamics corrections as well as contributions due to
the finite size of the nucleus (field shift) and finite mass of the nucleus (recoil effect) are evaluated.
Relativistic calculations are performed by means of the configuration-interaction method in the
basis of the Dirac-Fock-Sturm orbitals using the Dirac-Coulomb-Breit Hamiltonian
