“…The study of nuclear processes induced by weakly bound nuclei such as 6 Li, 7 Li, 10 Be, 11 Be, has attracted plenary attention for years. Especially, the processes induced by 6 Li and 7 Li nuclei gained attention due to the break-up effect of 6 Li into d + α, and 7 Li into t + α which plays a crucial role in the elastic scattering of 6 Li and 7 Li, for a range of target nuclei at different energies. There are extensive experimental measurements and theoretical studies for 6 Li + 28 Si nuclear system, and the available data are classified into two categories: experimental data near the Coulomb barrier energy EC [1][2][3][4][5][6][7] and the data above EC [8][9][10][11][12][13][14].…”

Available experimental angular distribution data for 6Li+28Si elastic scattering in the energy range 16 – 318 MeV are re-analyzed phenomenologically on the basis of optical model using Woods-Saxon (WS) potentials for both real and imaginary parts, while the semi microscopic analysis was performed on the basis of cluster folding potential. Cluster folding potential was generated based on the appreciable cluster structure and breakup of 6Li into a deuteron orbiting a core of α-particle. Although several data sets in a wide range of energies are subjected to investigation, the theoretical calculations using the different concerned potentials are fairly reproduced the experimental data in the whole energy range. The extracted real and imaginary volume integrals and reaction cross sections values are compared to the previously reported ones and they found to be in a good agreement

“…The latter process is conjectured to be of minor importance in our case because of the rather low energies considered. Furthermore, it is conceivable that in the case of lzC-TLi scattering inelastic transfer of five nucleons (5Li) contributes significantly, in particular at low energies and large scattering angles as observed in other studies [34,35].…”

Abstract. Elastic and inelastic scattering in the system 7Li+ 7Li was investigated experimentally in the energy range of Elab=8-17 MeV applying the method of kinematic coincidence. Sizeable cross sections were observed in the whole energy range for inelastic excitation of a single 7Li nucleus to its first excited state at E* = 0.47761 MeV as well as for mutual excitation of both nuclei. Systematic optical model and both one-step and two-step DWBA calculations were performed with the aim of describing in a consistent manner all three channels studied. This was achieved with optical model potentials fitted simultaneously to all elastic scattering data. They were then used to generate form factors for both single and mutual inelastic scattering as well as distorted waves for DWBA description of inelastic scattering considering the same deformation length for all form factors. Potential parameters derived show, despite these constraints, a continuous ambiguity in case of volume absorption while those with surface absorption can be grouped in six distinct families each of them featuring continuous ambiguities. The impact of real and imaginary form factors on single inelastic excitation is reversed for potentials with volume and surface absorption, while mutual excitation is dominated by imaginary form factors.

“…Since there are not data in the literature for this reaction at incident energies close to the present experiment, we considered three different optical potentials obtained for the similar system 9 Be+ 7 Li, at energies between 24 MeV and 34 MeV [2,3]. All these potentials use standard Woods-Saxon shapes.…”
