Non-uniqueness of the amplitude reconstruction in the inverse scattering problem and a refinement of Hoehler's resonance clustering
A. Švarc
Reaction-amplitude reconstruction in the inverse scattering problem is limited by the bilinear form of all reaction observables. At fixed kinematics, N complex amplitudes contain 2…

Possible explanation of Hoehler's clustering: effective partial-wave mixing induced by truncation
A. Svarc
Hoehler noted that resonance poles obtained from different partial waves in scattering appear to bunch together near a small set of common complex energies, and suggested that…

Resonances extracted in truncated partial-wave analysis are effective mixtures of angular momenta (Possible implications for Höhler's clustering)
A. Švarc
In truncated partial-wave analysis one fits observables, not amplitudes, and the relevant observables are bilinear in the amplitudes. For angle-dependent observables from which par…
