Cluster folding optical potential analysis for 6Li+28Si elastic scattering

Abstract

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

Further investigation of 10,11B + 58Ni elastic scattering

“…potential strength by∼47% for 10 B and∼36% for 11 B to reproduce the experimental data. The same situation was also previously reported for nuclear systems induced by weakly bound nuclei such as 6,7 Li [21][22][23][24][25]. The angular distributions for three beryllium isotopes ( 9 Be, 10 Be, and 11 Be) elastically scattered from the 64 Zn target were analyzed in the framework of DFOM showed a difference in the extracted N r values from the fit [26].…”

Detailed analysis for 6Li+40Ca elastic scattering using different potentials

“…This well-known decrease in the potential strength of the DF and CF potentials to reproduce the experimental data could be compensated by the implementation of additional potential, namely, the dynamic polarization potential (DPP), which represents dynamic polarization. By studying the scattering of weakly bound nuclei [32][33][34][35][36], many attempts have been made to account for this potential. This DPP is a surface potential designed to simulate the polarization effect Table 5.…”

Extensive investigation of the 6Li + 27Al and 6He + 27Al systems using different models

“…The research conducted in this work complements our prior investigations [27][28][29][30][31][32][33][34][35] that were focused on the study of interaction mechanisms and the distinct characteristics of weakly bound projectiles scattered from different target nuclei at energies both below and above the E C . This paper is structured as follows: section 2 presents the various potentials used in the calculations.…”

“…This impact is simulated by the addition of a repulsive dynamic polarization potential (DPP) of a surface shape. Several attempts [27,29] were made to include this DPP in a phenomenological form, expressed as a repulsive surface WS shape identified by three parameters (V pol , r pol , a pol ), which are the potential depth, radius, and diffuseness of the DPP. As previously demonstrated, the 6 Li + 27 Al ADs were reasonably fitted using the (CFP Real + CFP Imag.)…”
