Abstract

Elastic scattering of α -particles on medium-weight nuclei 5 8 Ni is analyzed in the energy range approximately from 20 to 175 MeV/nucleon using the original six-parameter S-matrix model. Energy dependences of the model parameters as well as the total reaction cross-sections, nuclear rainbow angles and Fraunhofer crossover angles are studied. Behaviors of the quantum deflection function and the S-matrix modulus are investigated as well. Regular behavior of the studied quantities indicates the consistency of the model and the reliability of the obtained parameters. The results are compared to the ones obtained from the optical model. Acceptable values of χ 2 ∕ N obtained in calculations by the S-matrix model demonstrate the applicability of this model in the entire considered energy range. [ABSTRACT FROM AUTHOR]
