%X The formalism of quantum systems with diagonal singularities is applied to describe scattering processes. Well defined states are obtained for infinite time, which are related to a ''weak form'' of intrinsic irreversibility. Real and complex generalized spectral decompositions of the Liouville-Von Neumann superoperator are computed. The physical meaning of ''Gamov states'' is discussed.
