Abstract: Reaction cross sections are calculated using the Coulomb-modified Glauber model for deformed target nuclei. The deformed nuclear matter density of the target is expanded into multipoles of order k =0, 2, 4. The reaction cross sections for 12 C+ 27 Al, 20 Ne+ 27 Al, 12 C+ 64 Zn, 12 C+ 90 Zr, 40 Ar+ 238 U and 20 Ne+ 235 U are studied at energy range (10–1000 MeV nucleon −1 ). The most significant effects in the intermediate energy range are the Coulomb field and in-medium effects that modified the trajectory of the incident beams. Introducing the deformation effect beside the Coulomb field and in-medium effects improves the agreement with the experimental data and two empirical parameterizations in the case of not finding experimental data. Moreover, it is shown that the enhancement of the reaction cross sections is attributed to fixed orientation in deformed nuclei.
