Abstract: Abstract We investigate a reaction-diffusion system which consists of a set of three partial differential equations. Due to the reaction kinetics the system can be referred to as a 1-activator-2-inhibitor system. We show, that such systems axe capable of supporting localized moving structures, so called quasi-particles. For certain parameters it is possible to predict the propagation speed of these solutions as well as their behaviour in scattering processes. In more general cases we have carried out simulations which reveal different scattering results depending on the parameters. We find annihilation, reflection and merging of particles.
