Abstract

Transition probabilities for lanthanide ions (La2+, Ce+, Ce3+, Pr2+, Nd2+, Sm2+, Tb2+, Dy2+, Ho2+, Er2+, Tm+, Tm2+, Yb+, Yb2+, Yb3+, Lu+ and Lu2+) have been calculated with a relativistic Hartree-Fock approach taking core-polarization effects into account. The theoretical results have been compared with experimental lifetimes measured using a time-resolved laser-induced fluorescence technique. The results obtained so far are stored in D.R.E.A.M., a database of astrophysical interest.
