Abstract：
A method to calculate reaction cross section based on the Glauber model is depicted in this paper. In the method, the density factor of Glauber model is modified and it is used to calculate the excitation function of proton-rich isotopes with same neutron number of n=3. Comparing the excitation function with experimental data, we found that, at above 100 MeV/u energies, the both excitation functions calculated by using the modified and the HO density factor are consistent very well with the experimental data. But, at the energies below 100MeV/u, the results calculated with modified density factor are close to the experimental data than that with HO distribution.
