Abstract
The fluorescence of N2(B3 PI(g)) and N2(C3 PI(u)) states is observed i n a time afterglow. This fluorescence is due to repopulation via pooli ng reaction of N2(A3 SIGMA(u)+) state. From a kinetic model, it is sho wn that the N2(C3 PI(u)) characteristic decay time depends on the atom ic nitrogen density. Atomic density is deduced from the observed fluor escence of N2(C3 PI(u)) for density higher than 5 x 10(13) cm-3. This density increases with pulse duration and current intensity.
