✦ Synopsis
Rotationally inelastic collisions in the b 31-[ lu state of Na 2 are observed in a free jet expansion by means of two-step laser excitation, using a mixed singlet-taiplet level as a gateway. The evolution of the occupation of collisionally populated levels and of the primary excited level are studied as functions of the downstream distance, yielding the effective lifetimes of these levels. Possibilities are discussed to produce molecules in long-lived levels of the b 3I-Iu state by means of rovibrational relaxation in such a free-jet apparatus.
