Energies of the 700 lowest levels in have
been obtained using the multiconfiguration Dirac-Fock method.
Configuration interaction method on the basis
set of transformed radial orbitals with variable parameters taking into
account relativistic corrections in the Breit-Pauli approximation
was used to crosscheck our presented results.
Transition
probabilities, oscillator and line strengths are presented for
electric dipole (E1), electric quadrupole (E2) and magnetic dipole (M1)
transitions among these levels.
The total radiative transition probabilities from each level are also provided.
Results are compared with data compiled by NIST and with other
theoretical work.
Key words: atomic data
