Abstract: | Accurate lifetimes measured by means of the cascade-free method based on laser excitation of a fast ion beam preexcited in a carbon foil are reported for four 2p 3d levels in NII. The lifetime results are: τ(2p 3d 3 D 1 0 )=0.209±0.007 ns, τ(2p 3d 3 D 2 0 )=0.219±0.007 ns, τ(2p 3d 3 D 3 0 )=0.217±0.005 ns, and τ(2p 3d 1 P 1 0 )=0.410±0.017 ns. These results are compared to theoretical and experimental lifetimes reported previously. |
