Title of program: PHASESHIFT ANALYSIS Catalogue Id: ABGB_v1_0 Nature of problem For elastic scattering the differential cross section and the polarization are determined by the elements of the S-matrix. The S- matrix can be parametrized in terms of complex phases. Generally the complex phases are slowly varying functions of energy. Only when near resonances will the phases, corresponding to the spin and parity of the special resonance, show specific anomalies, which sometimes allow the determination of spin and parity of the resonance.
