Analysis of heavy ions elastic scattering using the double folding cluster model

Analysis of cross sections using various nuclear potential

“…This approach seems to agree with the previous work done by Michaud [10] who suggested the calculation of optical model with a shallow potential containing a soft repulsive core for the 12 [11] have carried out the study on an α-α double folding cluster potential (DFC) to describe the fusion cross sections, astrophysical S-factor and angular distribution for the 16 O+ 16 O system. It shows that this potential can describe the broad features of the fusion, S-factor and elastic-scattering angular distribution data simultaneously.…”

“…The 12 C and 16 O considered in this work composed of an integer number (m) of α-particles, i.e., . Thus, such nuclei can demonstrate an α-cluster structure [15].…”

“…However, recent progress in development of theoretical models to calculate the fusion reactions especially for heavy-ion reactions also shows another challenge. Studies on heavy ion fusion cross section give significant impact on astrophysical environment through the main reactions such as 12 C+ 12 C, 12 C+ 16 O and 16 O+ 16 O. These reactions involve in the carbon and oxygen burnings which are important for the late stages of evolution of stars [1].…”

“…However, it has been stressed that the hindrance effect in carbon and oxygen burning is still not well established since the experimental data of fusion cross section for these reactions are still not low enough to confirm the existence. Furthermore, Mişicu and Carstoiu have reinvestigated the fusion cross section using the double-folding heavy-ion potentials and they do not find any sign of the existence of the hindrance effect on 12 C and 16 O reactions [8]. Hence, more experimental evidence and better theoretical treatments are needed to answer these questions.…”

“…It plays an important role in reproducing the experimental results for elastic and inelastic scattering [11,12]. The exchange part can be written to a good approximation in the form [10] …”
