[en] An accurate value for the radiative lifetime of the 2s2p2(4P)3s3P2 level in N II has been obtained using the beam-foil-laser spectroscopy method. The result (T = 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.
