Abstract : The nucleon-nucleus and nucleus-nucleus reaction cross-sections are calculated according to the optical model and compared to observations at high energies. The optical model is able to predict the existing experimental data on the assumptions that the effective collision cross section in nuclear matter is equal to the free N-N total collision cross section and the nucleon distribution in a nucleus is similar to its change distribution. The observed nucleonFe reaction cross section is significantly lower than the predicted value. It appears that both the observed pion-He cross section and the reaction cross section of alpha-particles in emulsion are larger than the predicted values.
