DDM3Y Folding Potential Model For ¹⁶O+²⁰Ne,²⁰Ne+²⁰Ne And α+²⁴Mg Heavy-ions Scattering

The heavy-ion scattering is one of the important topics in the field of nuclear physics. The nucleus-nucleus interaction potential is particularly important to describe the heavy-ion scattering. The folding model has been widely used to provide the real part of optical potential for heavy-ion scattering. In this thesis, using the DDM3Y folding potential model, we have analyzed the elastic 160+20Ne scattering at the energies of center of mass 24.5,27.9,28.2, 29.1,31.7,32.1,33.0,35.5 MeV, elastic 20Ne+20Ne scattering at incident energies of 62.1, 64.1,66.1,68.1,69.9,72.1,74.5 MeV, and elastic a+24Mg scattering at incident energies of 22.2,28.5,42.0,50.0,54.1,65.7,81.0,104.0,120.0 MeV.The elastic scattering angular distributions and excitation function at θ= 90° of 16O+20Ne and 20Ne+20Ne system can be reasonably described when the renormalization factors Nr are respective in the range of 0.30< Nr< 0.60,0.70< Nr< 0.95,0.95< Nr< 1.20 and 1.40< Nr< 1.70. The values of volume integral for the imaginary part of the optical potential are similar in the same energy and consistent with those obtained by other studies. For the elastic α+24Mg scattering, the calculated angular distributions have no oscillations in the large angles and cannot reproduce the experimental data when the renormalization factor Nr in the range 0.30< Nr< 0.60, while the calculated angular distributions are consistent with the experimental data when the renormalization factors Nr are respective in the range of 0.70< Nr<0.95,0.95< Nr< 1.20 and 1.40< Nr< 1.70. The scattering date show rainbow structure at the energy of 50 MeV, and a very deep real part of the optical potential can describe the rainbow structure better.The results of this thesis show that, the elastic 160+20Ne,20Ne+20Ne and α+24Mg scattering are well described by the DDM3Y folding potential model. Different depths of real part of optical potential can reasonably describe the elastic 16O+20Ne and 20Ne+20Ne scattering, and the values of volume integral for the imaginary part of the optical potential are similar in the same energy. For the elastic α+24Mg scattering, the calculated angular distributions have no oscillations in the large angles and cannot reproduce the experimental data with a very shallow real part of the optical potential, while the experimental data can be reproduced with other depths of real part of optical potential. And a very deep real part of the optical potential can describe the rainbow structure better at the energy of 50 MeV.
