In the theory of simple scattering systems we consider the wave operators \({W^ \pm } = \mathop {s - \lim }\limits_{t \to \pm \infty } {e^{it{H_2}}}{e^{ - itH1}}\) and the scattering operator S=(W+)*W- where H 1 H 2 are selfadjoint operators in a Hilbert space h describing the unperturbed and perturbed systems (see Jauch [12]). W ± are isometric and intertwine H 1 and H 2 (H 2 W ± ⊃ W ± H 1 ) whenever they exist. S is unitary if and only if the ranges of W ± are identical.
