[en] A new set of transition probabilities is proposed for Xe IX.They have been calculated by two different theoretical approaches i.e. a fully relativistic multiconfiguration Dirac–Fock (MCDF) method and a partly relativistic Hartree–Fock (HFR) approach takingcore-polarization effects in to account. Their accuracy has been evaluated through comparisons with lifetimeme asurements for 11 levels performed using beams of Xeþ ions produced by a 2 MVV an de Graaff accelerator. The agreement theory-experimentis nice for most of the levels and gives more weight to the theoretical models used for the calculations and, consequently,to the new transition probabilities
