Introducing a Global Optical Model Approach for Analysing 16O +16O Elastic Scattering at 5-10MeV/nucleon Region

35980

In this paper, the experimental data on elastic scattering of the 16O +16O reaction for the energy range 5-10 MeV/nucleon have been analyzed within the optical model (OM) formalism by using the phenomenological potential forms in Fresco code. When developing the shape of the nuclear potential for the calculations, we have used the Woods-Saxon (WS) or Woods-Saxon squared (WS2) potentials for the imaginary part together with a WS2 type real part. Although most of the previous OM analyses using phenomenological potentials have provided reasonably good fits with the experimental measurements, none of them could completely relate the behavior of the imaginary potential to the energy of the projectile yet. However, we have managed to introduce two analyses that can keep the real potential parameters almost constant and suggest a linear expression for the depth of the imaginary part of the nuclear potential depending on the incidence energy. Thus, 16O+16O system within this wide energy range has been described globally by the optical potentials having a deep, attractive real potential part and a weaker, energy dependent absorptive imaginary potential part. It has been also shown that, our calculations with these potential forms can reproduce the experimental elastic scattering angular distributions successfully and the maxima and minima are predicted correctly for most of the energies.
