摘要：

We have measured the lifetime of the a" 1-SIGMA-g+ (v = 0) level of N2 by monitoring through laser-induced vacuum ultraviolet fluorescence its population as a function of time after pulsed-electron excitation. The lifetime was measured for several rotational levels and found to be independent of the rotational level. The average lifetime is 3.49(10)-mu-s. This lifetime suggests that predissociation, not radiation, is the main decay mode for this metastable level.
