- Radiative lifetimes of 11 levels in Cd I belonging to the 5s5p <sup>1</sup>p<sup>o</sup><sub>1</sub> and 5snd <sup>3</sup>D<sub>1,2</sub>(n=6-9) and 5sns <sup>3</sup>S<sub>1</sub> (n=7,8) series, and of 5 levels of Cd II belonging to the 4d<sup>10</sup>5p <sup>2</sup>p<sup>o</sup><sub>1/2,3/2,</sub> 4d<sup>10</sup>6s <sup>2</sup>S<sub>1/2,</sub> and 4d<sup>10</sup>5d <sup>2</sup>D<sub>3/2,5/2</sub> configurations were measured using the time-resolved laser-induced fluorescence technique. Free neutral and singly ionized cadmium were generated by laser ablation. Single- or two-step excitation processes were used to populate the levels under study. Transition probabilities and oscillator strengths for Cd I and Cd II transitions were also deduced by combining the experimental lifetimes and theoretical branching fractions obtained in multiconfigurational relativistic Hartree-Fock calculations, taking core-polarisation effects into account
