    "abstract": "We show that a single-mode squeeze operator S(z) being an unitary operator\nwith a purely continuous spectrum gives rise to a family of discrete real\ngeneralized eigenvalues. These eigenvalues are closely related to the spectral\nproperties of S(z) and the corresponding generalized eigenvectors may be\ninterpreted as resonant states well known in the scattering theory. It turns\nout that these states entirely characterize the action of S(z). This result is\nthen generalized to N-mode squeezing.",
