Abstract
Energies and excitation probabilities of compressional and vortical co llective 1-states are calculated in the frame of the time-dependent Ha rtree-Fock theory. The method of Wigner function moments is used to fi nd collective solutions of an equation for a density matrix. Good agre ement with experiment is obtained for the low-energy isoscalar dipole resonance in Pb-208. The toroidal excitation is predicted.
