We study final states in the scattering of kinks and antikinks of the field-theoretic model. We use the initial conditions in the form of two, three or four static or moving kinks. In the numerical experiments we observe a number of different processes such as emergence of static and moving oscillons, change of the kink’s topological sector, scattering of an oscillon by a kink, production of kink–antikink pairs in oscillon–oscillon collisions. In antikink–kink collisions for asymmetric kinks, we found resonance phenomena – escape windows.
