Working within the framework of the Coulomb-modified Glauber model, we analyze the total reaction cross-section (sigma R) for He-3-particles from Be-9, C-12, O-16, Si-28, Ca-40, Ni-58,Ni-60, Sn-112,Sn-116,Sn-120,Sn-124, and Pb-208 at 96.4, 137.8, and 167.3MeV. Our calculations i) involve the realistic form factors for the colliding nuclei, and ii) emphasize the parametrization of the basic (input) NN amplitude, which may be used for a wide range of angles. The results are found to provide quite a satisfactory account of the sigma R data in all the cases. Moreover, we have also demonstrated the importance of the higher-momentum transfer components of the NN amplitude in providing a simultaneous description of the elastic angular distribution, covering large scattering angles, and the sigma R data for He-3-and alpha-nucleus systems in the considered energy range.
