Identical collision partners in the coherent control of bimolecular reactions

The coherent control of bimolecular processes typically requires that the s ystem be initiated in a superposition of correlated translational and inter nal reactant states. We show that by colliding identical molecules one bypa sses many of these complexities, allowing for direct studies of coherently controlled collision phenomena.
