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 5s5d3D3, 16.29 \± 0.24 ns; 5s5d3D2, 16.34 \± 0.13 ns; 5s5d3D1, 16.49 \± 0.10 ns; 5p2 3P2, 7.89 \± 0.05 ns; and 5s4f F13\°, 34.2 \± 0.4 ns.
