Direct experimental reconstruction of the pp elastic scattering amplitudes between 447 and 579 MeV.

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