Spatial shift produced in scattering process of lattice soliton is studied in the Fermi-Pasta-Ulam(FPU) model with anharmonic limit potential.Kink-shaped and antikink-shaped lattice solitons areexcited by kicking one single particle.Different behaviors are discovered in two types of head-on collision: kink-kink-shaped collision and kink-antikink-shaped collision.
