Abstract
A theory of nonanalytic (long-range) exchange interaction between an e lectron and a hole is developed for zero-dimensional excitons in semic onductor nanostructures. Two particular cases are considered in detail : (i) that of exciton confined in a spherical nanocrystal and (ii) a q uantum-well exciton localized as a whole on an anisotropic island of w ell-width monolayer fluctuation.
