Nuclear Interaction Radii for Light Exotic Nuclei

We developed a simple model to calculate the interaction radii for light neutron-rich nuclei based on Coulomb-modified Glauber model. Considering a relation of surface diffuseness of neutron distribution with the neutron separation energy of nucleus, the large increasing of nuclear interaction radii for exotic nuclei (such as ⁶He, ⁸He, ¹¹Li, ¹¹Be) on ¹²C target can be reasonably explained.
