Quasiclassical trajectories have been used to compute state-to-state energy transfer cross sections in collisions of He with H/sub 2/ initially in high vibrational--rotational states at 0.5 eV collison energy. The results show that for high rotational states (J> or =8) there is significant enhancement of the cross section for rotational energy transfer due to initial vibrational excitation. There is also enhancement of vibrational energy transfer by high initial rotational excitation. Rotational--vibrational energy transfer is the dominant mechanism for relaxation from initial high v, J states.
