Abstract
An accurate value for the radiative lifetime of the 2s 2p2(4P) 3s P-3( 2) level in N II has been obtained using the beam-foil-laser spectrosc opy method. The result (tau = 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 p resent time.
