“…Yongli Xu et al [21] performed a systematic global optical model description for 6 Li projectiles scattered elastically from targets ranging from 24 Mg to 209 Bi at energies below 250 MeV. The obtained global optical potential from this study was found to be applicable for different elastic scattering processes induced by 6 Li.…”

“…The data at high energies [8][9][10][11][12][13][14] were also subjected to various optical model (OM) and DF analysis. The 6 Li + 28 Si system has been subjected to several theoretical studies [15][16][17][18][19][20][21] recently, which were devoted to investigating this nuclear system either at low and high energies using different pure OM and DF potentials. M. Anwar [17] analyzed the experimental angular distributions of 6 Li scattered elastically by different targets − 24 Mg, 28 Si, 40 Ca, 48 Ca, 58 Ni, 90 Zr, and 11 6Sn -at E lab ( 6 Li) = 240 MeV.…”

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

“…For comparison, we also perform CDCC calculations with GOPs of α [43] and d [44] and optical potential calculations with a Li GOP [45]. The α GOP of Avrigeanu et al [43] and d GOP of An et al [44] have been examined for their validities at low incident energies. They are well-suited for use in the current study.…”

“…In the low energy d induced reactions, elastic scattering angular distribution is sensitive to the surface term of the optical potential but nearly independent of the inner part. It can be observed that provides a repulsion correction to the real part of around =8.05 fm, which is the interaction radius of the surface imaginary part of d GOP [44]. Furthermore, deepens the imaginary part of d optical potentials around .…”

We present a systematic study of $^{6}$Li elastic scattering and total reaction cross sections at incident energies around the Coulomb barrier within the continuum discretized coupled-channels (CDCC) framework, where $^{6}$Li is treated in an $\alpha$+$d$ two-body model. Collisions with $^{27}$Al, $^{64}$Zn, $^{138}$Ba and $^{208}$Pa are analyzed. The microscopic optical potentials (MOP) based on Skyrme nucleon-nucleon interaction for $\alpha$ and $d$ are adopted in CDCC calculations and satisfactory agreement with the experimental data is obtained without any adjustment on MOPs. For comparison, the $\alpha$ and $d$ global phenomenological optical potentials (GOP) are also used in CDCC analysis and a reduction no less than 50$\%$ on the surface imaginary part of deuteron GOP is required for describing the data. In all cases, the $^6$Li breakup effect is significant and provides repulsive correction to the folding model potential. The reduction on the surface imaginary part of GOP of deuteron reveals a strong suppression of the reaction probability of deuteron as a component of $^{6}$Li as compared with that of a free deuteron. A further investigation is made by taking the $d$ breakup process into account equivalently within the dynamic polarization potential approach and it shows that $d$ behaves like a tightly bound nucleus in $^{6}$Li induced reactions.

“…Recently, the global phenomenological optical model potentials for 6 Li, 7 Li and 8 Li have been proposed [29,30,31] which have been used for entrance 7 Li+ 124 Sn and exit 6 Li+ 125 Sn (for stripping) and 8 Li+ 123 Sn (for pickup) channels. We refer the results of these calculations as CRC1.…”

The relative importance of neutron transfer and breakup process in reaction around Coulomb barrier energies have been studied for the 7 Li+ 124 Sn system. Coupled channel calculations have been performed to understand the one neutron stripping and pickup cross sections along with the breakup in the 7 Li+ 124 Sn system. The systematics of one and two neutron striping and pickup cross sections with 7 Li projectile on several targets show an approximate universal behaviour that have been explained by a simple model. Complete reaction mechanism have been studied by comparing the reaction cross sections with cumulative cross sections of total fusion and one neutron transfer.
