We consider the scattering of small, identical, wave pulses, that are equivalent to a sequence of particles, and find that kink-antikink pairs are created for a large region in parameter space. We also find that scattering at {\it low} velocities is favorable for creating solitons that have large energy compared to the mass of a particle.4 pages, 2 figures.
