Abstract
Results are presented which have been obtained by combined analysis of experimental data on differential cross sections and polarisations of elastic scattering of protons from a 13C nucleus at energies of 13.5, 14.5, 16, 16.75 and 17.5 MeV. The analysis was made in terms of the optical model using the phenomenological real potential and the potential of the folding model. A set of energy-dependent optical parameters has been found which gives a better description of the data in the 10-20 MeV range compared with the set found earlier.
