Abstract :
[en] A detailed investigation of radiative parameters for electric dipole (El) transitions is presented for the ions Ra II, Ac 111, Th IV and U VI along the francium isoelectronic sequence. The pseudo-relativistic Hartree-Fock (BFR) method including core-polarization effects is used for the calculations. Comparisons with multiconfigurational Dirac-Fock (MCDF) calculations show that the most important relativistic effects are taken into account. In view of their importance in nuclear laser spectroscopy, forbidden rates (transitions M1 and E2) in Th IV are also reported in this paper.
