The new study of differential cross sections of 13 C( α,α' ) 13 C inelastic scattering at E α =29 MeV with the excitation of the 9.90 MeV state of the initial nucleus has been carried out. Modified diffraction model analysis showed that the root-mean-square (RMS) radius of the nucleus at this level might be approximately 20% less than the one of the ground state. We have showed the possibility of the existence of various states in the structure of the 13 C nucleus.
