    "abstract": "Starting from an effective Skyrme interaction we present a method to take\ninto account the coupling between one- and two-phonon terms in the wave\nfunctions of excited states. The approach is a development of a finite rank\nseparable approximation for the quasiparticle RPA calculations proposed in our\nprevious work. The influence of the phonon-phonon coupling on energies and\ntransition probabilities for the low-lying quadrupole and octupole states in\nthe neutron-rich Sn isotopes is studied.",
