Abstract

Working within the framework of the Coulomb-modified Glauber model, we analyze the total reaction cross-section ( for ³He -particles from ⁹Be , ¹²C , ¹⁶O , ²⁸Si , ⁴⁰Ca , ^{58, 60}Ni , ^{112, 116, 120, 124}Sn , and ²⁰⁸Pb 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 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 data for ³He - and -nucleus systems in the considered energy range.
