All calculations of this study were carried out by using a development version of the DIRAC program ; the precise version and build information are shown in the output files, see ref . Our calculations are based on the spin-free (SF) and spin-orbit (SO) relativistic Hamiltonians. For the one-electron part of the Hamiltonian, the exact two-component Hamiltonian (X2C) is employed for both SF and SO relativistic calculations. For the two-electron term, the non-relativistic Coulomb operator is employed for the SF calculation, and the Gaunt term is added in the atomic mean-field approximation (AMFI) scheme for the SO calculation . The nuclear potential is described by the Gauss-type finitesize nuclear model . For all elements in this study, dyall.v3z basis sets are employed in the uncontracted form.
