AB We investigate the nonparametric, pure ac driven dynamics of nonlinear Klein-Gordon solitary waveshaving an internal mode of frequency Vi . We show that the strongest resonance arises when the drivingfrequency d   Vi 2, whereas when d   Vi the resonance is weaker, disappearing for nonzero damping.At resonance, the dynamics of the kink center of mass becomes chaotic. As we identify the resonancemechanism as an indirect coupling to the internal mode due to its symmetry, we expect similar resultsfor other systems.
