A Discussion on Whether ^15-20C Are All Skin Nuclei via Isospin-dependent Boltzmann-Langevin Equation

A new attempt of calculation for the total reaction cross sections (σ_R) has been carried out within the isospin-dependent Boltzmann-Langevin equation in the intermediate energy heavy-ion collision of isotopes of C. The σ_R of both stable and exotic nuclei are reproduced rather well. The incident energy and isospin dependencies of σ_R have been investigated. It is found that the isospin effect is comparatively remarkable at intermediate energy. It is also found that ^15-18C are neutron skin nuclei but for ¹⁹C and ²⁰C we cannot draw a conclusion whether they have halo structures.
