摘要：
Lifetimes and excitation behaviour of a number of core excited quartet levels in neutral Na, produced by beam foil excitation, have been established. The present results have helped to resolve the discrepancy seen in the published lifetime values of the 3s4s P-4(5/2) and 3s3d P-4(5/2) levels. Further, a new line having a wavelength of 4343 angstrom displaying similar excitation behaviour to the known transitions between the quartet states has been observed. Its lifetime is measured to be 0.91 +/- 0.13 ns. It is suggested that this line is most probably due to a transition between the 3s(1P)3p P-2(3/2) and 3s2(1S) P-2(3/2) states.
