A tunable dye laser was used to populate selectively a single rotational-vibrational state of N 2 ( B 'E , u' = 0, N' = O-l 5 ) .

Fully converged quantum cross sections for 4He-D2 (u= l,i=O) vibrational reliaxation were determined using the coupled-states method and a modikied version of the Gordon-Secrcst surface. First-order forbidden rotational transitions play a si@fkant role, comparable to that observed previously for the
