    "abstract": "We calculate the spatial correlation of electrons and positrons emitted by\ninternal pair conversion of Coulomb excited nuclei in heavy ion collisions. The\nalignment or polarization of the nucleus results in an anisotropic emission of\nthe electron-positron pairs which is closely related to the anisotropic\nemission of $\\gamma$-rays. However, the angular correlation in the case of\ninternal pair conversion exhibits diverse patterns. This might be relevant when\ninvestigating atomic processes in heavy-ion collisions performed at the Coulomb\nbarrier.",
