Abstract
The UV and visible fluorescence of Na-2 molecules in a heat-pipe, exci ted by the frequency doubled radiation of a tunable mode-locked cavity -dumped cw dye laser was observed through a monochromator, using time- resolved single-photon counting. The effective lifetimes of the direct ly excited (CIIu)-I-1 state and the collisionally populated 2(3)II(g) and 2(1) Sigma(u)(+) states have been measured as a function of sodium -vapor pressure and argon pressure which yields the radiative lifetime s, the population mechanisms and the collisional quenching cross secti ons of the three states.
