Abstract: We have performed an experiment to demonstrate the approximate time reversalof a -chaotic- time evolution of atomic deBroglie waves. We use ultra coldatoms from a Bose-Einstein condensate in a quantum $\delta$-kicked rotorexperiment, and show that an initial state can be approximately re-created evenafter a period of -chaotic- evolution a number of kicks. As this mechanismonly works for a very narrow range of momenta, the net effect is a narrowing ofthe momentum distribution after the kick sequence.
