“…From the point of view of the reaction mechanisms, via our CDCC calculations it became clear once more that couplings to the continuum are strong and important. This fact was also verified in similar work on samarium, thorium and lead in [20][21][22][23]. However, to obtain a full insight into the reaction mechanism and how it is related to the predicted optical potential more work from the experimental and theoretical points of view is necessary.…”

“…Other measurements of elastic and quasi-elastic backscattering barrier distributions for weakly bound nuclei have been reported previously for heavy targets: 6,7 Li + 208 Pb [20], 6 Li + 144,146 Sm [21,22] and 6 Li + 232 Th [23] with the emphasis on the coupling effects rather than the energy dependence of the optical potential. The choice of almost spherical targets in the present case was based mainly on our intention to probe the potential without any strong interference from the structure of the involved nuclei.…”

Quasi-elastic backscattering of 6,7Li on light, medium and heavy targets at near- and sub-barrier energies

Abstract.We have performed precision elastic backscattering measurements for the weakly bound nuclei 6,7 Li on the medium and heavy mass targets 58 Ni, 116,120 Sn and 208 Pb at sub-and near-barrier energies (E c.m./Vbar = 0.6 to 1.3). Excitation functions of elastic scattering cross-sections have been measured at ±160• and ±170• and the corresponding ratios to Rutherford scattering and relevant barrier distributions have been extracted. These measurements complement recent work on a 28 Si target, for probing systematically the potential at sub-and near-barrier energies and relevant reaction mechanisms, while indicate a possible breakdown of the dispersion relation.

“…It has been shown that this interaction is able to describe the position of the 7 Li resonances as well as its width. It has been successfully used for the description of the breakup reaction of 7 Li with 59 Co [31], 144 Sm [34,35], 120 Sn [11]. Convergence of the calculations was achieved with 500 partial waves and a matching radius of 400 fm.…”

Experimental angular distributions for the 7 Li + 120 Sn elastic and inelastic (projectile and target excitations) scattering, and for the neutron stripping reaction, have been obtained at E LAB = 20, 22, 24, and 26 MeV, covering an energy range around the Coulomb barrier (V (LAB) B ≈ 21.4 MeV). Coupled channel and coupled reaction channel calculations were performed and both describe satisfactorily the experimental data sets. The 1 2 − state 7 Li inelastic excitation (using a rotational model), as well as the projectile coupling to the continuum (α plus a tritium particle) play a fundamental role on the proper description of elastic, inelastic, and transfer channels. Couplings to the one-neutron stripping channel do not significantly affect the theoretical elastic scattering angular distributions. The spectroscopic amplitudes of the transfer channel were obtained through a shell model calculation. The theoretical angular distributions for the one-neutron stripping reaction agreed with the experimental data.
