    "abstract": "Isoscalar and isovector monopole oscillations that correspond to giant\nresonances in spherical nuclei are described in the framework of time-dependent\nrelativistic mean-field theory. Time-dependent and self-consistent calculations\nthat reproduce experimental data on monopole resonances in 208Pb, show that the\nmotion of the collective coordinate is regular for isoscalar oscillations, and\nthat it becomes chaotic when initial conditions correspond to the isovector\nmode. Regular collective dynamics coexists with chaotic oscillations on the\nmicroscopic level. Time histories, Fourier spectra, state-space plots, Poincare\nsections, autocorrelation functions, and Lyapunov exponents are used to\ncharacterize the nonlinear system and to identify chaotic oscillations.\nAnalogous considerations apply to higher multipolarities.",
