Theoretical lifetimes, calculated with inclusion of core-polarization effects, have been determined for five 4f76p levels of doubly ionized gadolinium. They agree quite well with recent experimental values measured by time-resolved laser-induced fluorescence spectroscopy. From this agreement, the accuracy of a first set of Gd III transition probabilities, calculated for 4f75d–4f76p and 4f76s–4f76p transitions of astrophysical interest, has been assessed.
