We calculate the spatial correlation of electrons and positrons emitted by internal pair conversion of Coulomb excited nuclei in heavy-ion collisions. The alignment of the nucleus results in an anisotropic emission of the electron-positron pairs that is closely related to the anisotropic emission of {gamma} rays. However, the angular correlation in the case of internal pair conversion displays additional features which provide the possibility for a deeper understanding of the nuclear structure. Our results are of particular interest for the electron-positron coincidence experiments currently analyzed at GSI (Darmstadt) and at Argonne. {copyright} {ital 1996 The American Physical Society.}
