Forward differential cross sections for π − p elastic scattering at 1.0, 1.5 and 2.0 GeV/ c show that the square of the imaginary parts of the nuclear scattering agrees with the optical theorem prediction within ±3%, when averaged over the three momenta.

Direct Experimental Reconstruction of the $P P$ Elastic Scattering Amplitudes Between 447-{MeV} and 579-{MeV}

Hausammann, R. ; Heer, E. ; Hess, R. ; et al.

Inspire Record 285139 DOI 10.17182/hepdata.23146

A direct experimental reconstruction of the five complex pp elastic-scattering amplitudes has been performed at 447, 497, 517, 539, and 579 MeV. The reconstruction is done over the c.m. angles from 38° to 90° and is based on either 11 or 15 spin observables depending on the angular range. The reconstructed amplitudes are presented and compared to phase-shift analysis. A smooth energy behavior is observed for the amplitudes.
