Experiments are presented which demonstrate the conversion of certain integrals of motion during Hamiltonian chaos, where the conservation of some of the integrals has been broken by the overlap of resonances. Experimentally, conservation laws are demonstrated through the observation of restrictions on transport, in phase space, of chaotic trajectories. Transport of plasma ions during stochastic motion in an electrostatic wave is followed by means of laser-induced fluorescence on metastable "test particles" produced by optical pumping.
