Synchrotron motion with an external rf voltage modulation was studied experimentally. Beam particles, in the presence of electron cooling, were observed to damp to the basins of resonance islands, which were produced by the parametric resonance due to rf voltage modulation. The measured phase amplitudes of the centers of these resonance islands were found to agree well with theory.
