Abstract(s) :

(Anglais) In the present work, we report on experimental and theoretical determination of the decay rates from the 7s1/2 state in singly ionized lead. Lifetime measurements performed using time-resolved laser-induced fluorescence spectroscopy and lifetime computations carried out with the multiconfiguration Dirac-Fock method allow us to solve the discrepancies previously observed between theory and experiment for this level. New transition probabilities are proposed for the two depopulation channels, i.e. the 6p1/2-7s1/2 and 6p3/2-7s1/2 transitions of astrophysical interest in Pb II and Bi III, respectively.
