N2 - The techniques of linear response theory are applied to nuclear one-body dissipation. For leptodermous nuclei, the rate of energy dissipation is characterized by a kernel, γ, coupling the motion at different points in the nuclear surface. This kernel is simply related to the Green function for the nuclear potential. The spatial and thermal behavior of γ is investigated for semi-infinite nuclear matter and compared with classical formulas. Corrections for surface diffuseness are also estimated. For arbitrary nuclear shapes, an integral equation is given from which γ may be evaluated. This is then used to estimate curvature corrections to the planar results. Finally, extensions and limitations of our approach are discussed.
