Abstract：
A unified parametrized formula of total reaction cross section σ_R from low energy to intermediate and high energy has been proposed.Most of the experiment results in whole energy range can be reproduced by this parametrization.The relation of σ_R with neutron excess degree of freedom (N-Z) and the relation of interaction radius R with incident energy E_cm^-1/3 have also been discussed.
