We study the creation of solitons from particles, using the λ 4 model as a prototype. We consider the scattering of small, identical, wave pulses, which 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 low velocities is favorable for creating solitons that have large energy compared to the mass of a particle.
