Abstract Selective laser excitation was used to measure the radiative lifetimes of the ZnI triplet states 4sns 3 S 1(n=5–7) and 4snd 3 D 3,3 D 2 and3 D 1(n=4–6). These states were excited from the metastable 4s4p 3 P states, which were collisionally populated in an atomic beam. The values are compared with the results of other experimental methods (beam-foil, pulsed electron excitation, Hanle effect) and with theoretical calculations. The corresponding oscillator strengths are discussed with respect to the astrophysical determination of the Zn photospheric abundance.
