Phase-shift ambiguities for analytic amplitudes
Ambiguities in reconstructing a unitary elastic amplitude at fixed energy are investigated given the differential cross-section when one assumes analyticity in the cos theta plane. Strong hints are given that not more than a twofold nontrivial ambiguity is present. This is demonstrated for genuine e...
