Abstract

The differential cross-sections of the elastic and inelastic ¹³C + α scattering were measured at E(α) = 65 MeV. The radii of the states: 8.86 (1/2⁻), 3.09 (1/2⁺) and 9.90 (3/2⁻) MeV were determined by the Modified diffraction model (MDM). The radii of the first two levels are enhanced relatively that of the ground state of ¹³C, confirming the suggestion that the 8.86 MeV state could be an analogue of the Hoyle state in ¹²C and the 3.09 MeV state has a neutron halo. No enhancement of the radius of the 9.90 MeV state was observed.
