  "abstract": "We investigate the non-parametric, pure ac driven dynamics of nonlinear Klein-Gordon solitary waves having an internal mode of frequency $\\Omega_i$. We show that the strongest resonance arises when the driving frequency $\\delta=\\Omega_i/2$, whereas when $\\delta=\\Omega_i$ the resonance is weaker, disappearing for nonzero damping. At resonance, the dynamics of the kink center of mass becomes chaotic. As we identify the resonance mechanism as an {\\em indirect} coupling to the internal mode due to its symmetry, we expect similar results for other systems.",
