Abrupt Rise

It is shown that the abrupt rise of around 200 MeV/c in the real-to-imaginary ratio ρ of the forward scattering amplitude in low energy [Formula: see text] scattering is not due to the [Formula: see text] threshold or approximations in the treatment of the coulomb nuclear interference. The latter breaks down below Plab≈100 MeV/c. The possibility of a potential resonance is discussed.
