Abstracts

EN

We have calculated the energies of some low-lying levels (6d7s^2, 6d^2 7s, 6d7s7p and 6d^27p) and electric dipole transition parameters (wavelengths, oscillator strengths and transition probabilities) between them for neutral actinium (Z=89). In the calculations, the correlation and relativistic effects are considered by multiconfiguration Hartree-Fock method within the framework Breit-Pauli Hamiltonian. The results obtained are compared with the available experimental and theoretical works in the literature.
