Abstract

We have measured mean lives of five levels in three different configurations in Sr i by exciting them selectively in fast beams of neutralized ions by light from an argon-ion laser, and following their time-resolved decay downstream. The mean lives of these levels are 5s5d ³D₃, 16.29 ± 0.24 ns; 5s5d ³D₂, 16.34 ± 0.13 ns; 5s5d ³D₁, 16.49 ± 0.10 ns; 5p^{2 3}P₂, 7.89 ± 0.05 ns; and $5s4f\hspace{0.17em}{{}^{1}F}_3^{°}$, 34.2 ± 0.4 ns.
