Badahdah Física, Astronomía y Matemáticas Heavy ion scattering Regge pole analysis Strong absorption models McIntyre and Frahn-Venter three-parameter models are used to analyze the experimental data of three elastic scattering reactions a+ 58Ni, a+ 116Sn and a+ 197Au at the same incident energy of 240MeV. The different a-scattering cases have the same number of minima and maxima in their oscillatory structures of angular distribution. The increase in the mass of target nucleus leads to a smaller nuclear deflection minimum and causes the corresponding angular distribution to become smoother and with steeper slope. The Coulomb damping of Fraunhofer oscillations has an effect accompanied with the increase of mass of target nucleus. The presence of semi-classical phenomena such as Fresnel and Fraunhofer diffraction patterns etc., has been found by analyzing the experimental data of elastic scattering reactions, 16O + 64Zn, 32S + 64Ni, and 58Ni + 27Al at several laboratory energies. The generalised Fresnel model can fairly reproduce the angular distribution of these reactions. Excellent fitting can be obtained using Regge pole model, especially at backward angles where the data can not be recovered by the other three models. The adopted theoretical models can reasonably account for the general pattern of the data, thus allowing us to extract important parameters from elastic scattering processes. The analysis also shows that the total reaction cross section has an energy-dependent trend similar to that found by other models. 2009 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46413564012 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4 Vol.39 |
