Abstract
It is common practice in scattering theory to correlate the position of a resonance peak in the cross section to the real part of a complex energy of a pole of the scattering amplitude. In this work, we show that the resonance peak position appears at the absolute value of the pole's complex energy rather than its real part. We further demonstrate that a local theory of resonances can still be used even in the cases previously thought to be impossible.
