Abstract
Collective vibrations in spherical nuclei are described in the framewo rk of time-dependent relativistic mean-field theory (RMFT). Isoscalar quadrupole and isovector dipole oscillations that correspond to giant resonances are studied, and possible excitations of higher modes are i nvestigated. We find evidence for modes which can be interpreted as do uble resonances. In a quantized RMFT they correspond to two-phonon sta tes.
