For a ''slowly'' time-dependent Hamiltonian system exhibiting ergodic motion, the volume inside the hypersurface on which the Hamiltonian equals a constant is an adiabatic invariant. It is shown that the error in the constant is diffusive and scales as (tau/sub C//t)/sup 1/2/, where tau/sub C/ is a certain correlation time of the ergodic motion, and tau is the time scale over which the Hamiltonian changes.
