| Resumo: | In this paper the scattering between a wobbling kink and a wobbling antikink in the standard 4 model is numerically investigated. The dependence of the nal velocities, wobbling amplitudes and frequencies of the scattered kinks on the collision velocity and on the initial wobbling amplitude is discussed. The fractal structure becomes more intricate due to the emergence of new resonance windows and the splitting of those arising in the non-excited kink scattering. Outside this phase, the nal wobbling amplitude exhibits a linear dependence on the collision velocity whereas the nal frequency is a decreasing function. By contrast, these magnitudes are almost independent of the initial wobbling amplitude. A theoretical analysis of this new scenario is carried out by applying the collective coordinate method. |
