THE FIRST IDENTIFICATION OF THE PROTON HALO IN THE EXCITED STATE OF 13N
Journal Title: Eurasian journal of physics and functional materials - Year 2017, Vol 1, Issue 1
Abstract
We demonstrate that the radii of excited nuclear states can be estimated using the (3He,t) charge-exchange reaction and relying on the modified diffraction model.The radius of the 13N excited state with an excitation energy of E*=2.37 MeV,which lies in a continuous spectrum, is determined. The radius of this state proves to be close to that of the mirror 3.09-MeV state of the 13C nucleus, which possesses a neutron halo but lies in a discrete spectrum. Thereby, we demonstrate that the 2.37-MeV state of the 13N nucleus has a proton halo. The analysis is based on published measurements of differential cross sections for relevant reactions.
