Abstract. A new attempt of calculation for the total reaction cross sections (σR) has been carried out within the isospindependent Boltzmann–Langevin equation in the intermediate energy heavy-ion collision of isotopes of C. The σR of both stable and exotic nuclei are reproduced rather well. The incident energy and isospin dependencies of σR 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.
