Abstract:
We demonstrate that the radii of excited nuclear states can be estimated using the (3He,t)(3He,t) charge-exchange reaction and relying on the modified diffraction model. The radius of the NN excited state with an excitation energy of E∗=2.73E∗=2.73 MeV, which lies in a continuous spectrum, is determined. The radius of this state proves to be close to that of the mirror 3.093.09-MeV state of the 13C13C nucleus, which possesses a neutron halo but lies in a discrete spectrum. Thereby, we demonstrate that the 2.372.37-MeV state of the 13N13N nucleus has a proton halo. The analysis is based on published measurements of differential cross sections for relevant reactions.
