It looks like an Exceptional Point but it isn’t

Dieter Heiss (University of Stellenbosch)

It is demonstrated that, in single particle potential scattering, the meeting point of resonance poles at zero energy under variation of the potential strength has some characteristics of an exceptional point, but it is not an EP under some more careful scrutiny. While this appears to be a mathematical curiosity it is of physical interest, e.g. in low energy neutron scattering in nuclear physics where the cross section shows a very special behaviour around zero energy.
