摘要：

Differential cross-sections of the elastic and inelastic C-13 + alpha scattering were measured at E(alpha) = 90 MeV. The root mean-square radii (< R-rms >) of C-13 nucleus in 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 compared to that of the ground state of C-13, confirming the suggestion that the 8.86 MeV state is an analogue of the Hoyle state in C-12 and the 3.09 MeV state has a neutron halo. Some indications to the abnormally small size of the 9.90 MeV state were obtained.
