    "abstract": "The work deals with one of the topics of collective motion. In the frame of\nNuclear Fluid Dynamics, a model which portrays the nuclear matter as a quantum\nelastic body, the torus-like motions and their associated energies are computed\nusing the thirteen moment approximation. The spin-dependent collective\nexcitations, with toroidal electromagnetic structure, are studied by means of\nthe Generalized Goldhaber-Teller model, with emphasize on the 1$^{-}$ spin-flip\nmode and its excitation in spherical nuclei by inelastic electron scattering.\nWe discuss the importance of toroidal contributions in the inclusive electron\nscattering $(e, e\u0027)$ and exclusive coincidence electron scattering $(e,\ne\u0027\\gamma)$. In order to extract the toroidal multipole, we use the\nbackscattering angles in the first mentioned reaction, and the separation of\nthe longitudinal/transverse interference in the second case. The introduction\nof a quantity which accounts for the deviations from the Siegert theorem, shows\nthe importance of toroidal quadrupole transitions at high-momentum transfer.",
