Abstract：
The effect of surface diffuseness of neutron distribution on total reaction cross section σR is discussed based on coulomb－modified Glauber model． Considering a relation of surface diffuseness of neutron distribution with the neutron separation energy of nuclei， the large increasing of nuclear total reaction cross section for exotic nuclei (such as ⁶He, ⁸He, ¹¹Li, ¹¹Be) on ¹²C target can be reasonably explained.The total reaction cross section for a large number of stable nuclear systems can also be reproduced over an energy range beginning witb the coulomb barrier to a few GeV/nucleon.
