The scattering of electrically neutral particles on such space-times is described by amplitudes that exhibit resonant behaviour when the scattering and deficit angles coincide. This, in turn, leads to ring-like structures where the cross sections are formally divergent (\"singular lensing\"). In this work, we revisi","authors_text":"Joannis Papavassiliou, Nick E.
