    "abstract": "We search for nonlinear effects in nuclear giant resonances (GRs), in\nparticular the isovector dipole and the isoscalar quadrupole modes. To that\nend, we employ a spectral analysis of time-dependent Hartree-Fock (TDHF)\ndynamics using Skyrme forces. Based on TDHF calculations over a wide range of\nexcitation amplitudes, we explore the collectivity and degree of harmonic\nmotion in these modes. Both GR modes turn out to be highly harmonic in heavy\nnuclei from A=100 on. There is no trace of a transition to irregular motion and\nmultiple resonances are predicted. Slight anharmonicities are seen for light\nnuclei, particularly for $^{16}$O. These are mainly caused by the spin-orbit\nsplitting.",
