Abstract

The differential cross-sections of the elastic and inelastic α + 13С scattering were measured at E(α) = 29 in U150M cyclotron of Institute of Nuclear Physics (Almaty, Kazakhstan) and E(α) = 65 MeV in K-130 cyclotron of University of Jyvaskyla (Jyvaskyla, Finland).

The first excited state of 13C nucleus is of special interest because, it is a state with increased radius, where we can talk about the structure of a neutron halo. The observed shift of Airy minima positions shows that the state of 8.86 MeV (1/2-) 13C nucleus and the state of 7.65 MeV (0+2) 12C have much in common and, with some confidence, these levels could be called analogues of each other.

The radii of the states: 3.09 (1/2+) and 8.86 (1/2-) were determined by the Modified diffraction model (MDM) at E(α) = 65 MeV and 3.09 (1/2+) at E(α) = 29 MeV.
