Abstract:We report on the lifetime measurement of the 6 1 Σ + g (7, 31) state of Na 2 molecules, produced in a heat-pipe oven, using a time-resolved spectroscopic technique. The 6 1 Σ + g (7, 31) level was populated by two-step two-color double resonance excitation via the intermediate A 1 Σ + u (8, 30) state. The excitation scheme was done using two synchronized pulsed dye lasers pumped by a Nd:YAG laser operating at the second harmonics. The fluorescence emitted upon decay to the final state was measured using a time… Show more
