A study is made of the general properties of scattering systems in which the motion is generated by a Hamiltonian of the form $H=H_0+V$, where smooth spatial and momentum cutoffs are made in $V$. The algebra of the asymptotic fields is studied and sufficient conditions are found for the existence of a scattering operator; some general properties of this operator are proved.
