Angular distributions for the electronic to vibrational rotational and translational energy (E-VRT) transfer process Na*(3p)+H/sub 2/,D/sub 2/..-->..Na(3s)+H/sub 2/(v',j') with product energy analysis have been measured for the first time. The differential cross sections are forward peaked, constant but small between 35/sup 0/ and 160/sup 0/ and very slightly increasing at 180/sup 0/. The observations can be qualitatively understood by a simple model for the particle motion on the attractive A/sup 2/B/sub 2/ excited-state surface with a hop to the repulsive X/sup 2/A/sub 1/ ground state.
