Zusammenfassung:	New experimental data on the inelastic scattering of α-particles on 13 C at and 90 MeV with the excitation of the 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 8.86 MeV state in 13 C and the Hoyle state in 12 C. 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 13 C has been tested by considering its isobar-analog 3/2 – 9.48 MeV state in 13 N. It has been found that these states have a normal non-increased radius.
