Synopsis We study the appearance of quantum vortices in the transition matrix element of single ionization collisions. We relax all the usual geometrical restrictions on the momenta of the final-state, and demonstrate that previously observed vortex points and lines correspond to 2D and 3D intersections of a much more complex structure: a quantum vortex surface. Finally, we theoretically evaluate this complex structure for the single ionization of hydrogen by positron impact.
