Radiative lifetimes of Cd I and Cd II excited states

Summary, in English

Radiative lifetimes of 11 levels in Cd I belonging to the 5s5p ¹p^o₁ and 5snd ³D_1,2(n=6-9) and 5sns ³S₁ (n=7,8) series, and of 5 levels of Cd II belonging to the 4d¹⁰5p ²p^o_1/2,3/2, 4d¹⁰6s ²S_1/2, and 4d¹⁰5d ²D_3/2,5/2 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
