An accurate value for the radiative lifetime of the 2s 2p2(4P) 3s 3P2 level in N II has been obtained using the beam-foil-laser spectroscopy method. The results (τ= 0.456±0.020 ns) is shorter than the beam-foil lifetime values reported previously for the 3s' 3P term. No theoretical value for the lifetime of this term is available at the present time.
