Energy Levels and Electric Dipole Transitions for Neutral Actinium (Z=89)
No full textWe have reported a relativistic multiconfiguration Dirac-Fock calculation including Breit and quantum electrodynamic contributions on the level structure of atomic actinium, Ac I (Z = 89). The computations have been carried out for the low 45 even and 60 odd-parity levels, and the electric dipole transition parameters (wavelengths, oscillator strengths and transition probabilities) for some transitions between these levels. Comparison has been also made with other results in available literature
