- Antikink-kink ($\bar{K}K$) collisions in the $\phi^6$ model exhibit resonant scattering although the $\phi^6$ kinks do not support any bound states to which energy could be transferred. In P. Dorey et al. [Kink-Antikink Collisions in the $\phi^6$ Model, Phys. Rev. Lett. 107, 091602 (2011)] it was conjectured that, instead, energy is transferred to a collective bound mode of the full $\bar{K}K$ configuration. Here we present further strong evidence for this conjecture. Further, we construct a collective coordinate model (CCM) for $\bar{K}K$ scattering based on this collective bound mode trapped between the $\bar{K}K$ pair which allows us to reproduce the full dynamics of $\bar{K}K$ scattering with striking accuracy. We also study kink-antikink ($K\bar{K}$) scattering and its description by a CCM. In this case a significant role of radiation is discovered.
