The phase shift analysis, done on the basis of the known measurements of thedifferential cross-sections of the p13C elastic scattering at the energy range250-750 keV, shows that it is enough to take into account only 3S1 wave in theconsidered energy region. The potential for the triplet 3S1 state in p13Csystem at the resonance energy 0.55 MeV corresponding to quantum numbers JpT =1-1 as well as the potential for the 3P1 bound state of 14N were constructed onthe basis of the obtained scattering phase shifts. The possibility to describethe experimental data of the astrophysical S-factor of the p13C radiativecapture at the energies 0.03-0.8 MeV was considered within the potentialcluster model with the forbidden states. It was shown that we properly succeedin explanation of the energy behavior of the astrophysical S-factor for thep13C radiative capture at the resonance energy range 0.55 MeV (laboratorysystem).
