The author considers a system of free fermions at zero temperature perturbed by a local interaction. Assuming the existence of a unique gorund state for the perturbed system, via some techniques similar to those in [\textit{J. Derezinski} and \textit{C. Gérard}, Rev. Math. Phys. 11, No. 4, 383--450 (1999; Zbl 1044.81556)], the wave operators for this system are constructed and the asymptotic completeness is proved.
