T. Bastin et al., MEASUREMENT OF THE 2S 2P(2)(P-4) 3S P-3(2) LIFETIME IN N-II BY BEAM-FOIL-LASER SPECTROSCOPY, Journal de physique. II, 3(10), 1993, pp. 1479-1483
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.
