New experimental data on the inelastic scattering of α-particles on 13C at (Formula presented.) and 90 MeV with the excitation of the (Formula presented.) state are reported. Data are analyzed using the modified diffraction model. The determined rms radius of this state coincides within errors with the radius of the (Formula presented.) 8.86 MeV state in 13C and the Hoyle state in 12C. This result is an argument for a similar structure of these states. The unusual result for the compact 3/2– 9.90 MeV state in 13C has been tested by considering its isobar-analog 3/2– 9.48 MeV state in 13N. It has been found that these states have a normal non-increased radius.
