The explicit expressions of Amado et al. for elastic scattering observables for protons at intermediate energies have been applied to data at 500 and 800 MeV. Analyses were performed using both the analytic form of the solutions and data-to-data relations. Good fits are obtained with few parameters; however, these seem to have only phenomenological significance.
