The most prominent collective modes excited in deep-inelastic reactions are reviewed, and the natural hierarchy provided by their characteristic relaxation times is described. A model is presented which treats the relaxation of the mass asymmetry mode in terms of a diffusion process. Charge distributions and angular distributions as a function of Z calculated with this model are in good agreement with experimental data. An extension of this diffusion model which treats the transfer of energy and angular momentum in terms of particle transfer is described, and is successfully compared with experimental γ-ray multiplicities as a function of both Q-value and mass asymmetry. The problem of angular momentum transfer is again considered in connection with the sequential fission of heavy, deep-inelastic fragments and the excitation of collective modes in the exit channel is suggested. Lastly, the role of the giant El mode in the equilibration of the neutron-to-proton ratio is discussed.
