摘要：

We have obtained accurate values for the radiative lifetimes of the 2p 3d 1D0 and 2p 3d P-3(2)0 levels in NII by the cascade-free beam-foil-laser spectroscopy method. Our results are tau(2p 3d 1D0)=0.346 +/- 0.012 ns and tau(2p 3d P-3(2)0=0.457 +/- 0.020 ns. Comparison of these results with experimental and recent theoretical lifetimes reported previously is also made.
