Abstract

Experimental \({}^{7}\)Li\(+ {}^{27}\)Al elastic scattering angular distributions in the 6–89 MeV laboratory energy range have been re-analysed using different phenomenological and microscopic potentials to investigate the cluster nature of the weakly-bound \({}^{7}\)Li projectile and the associated break-up effect on the elastic scattering data. The consistency of the results obtained within the various implemented potentials was also analysed. A new microscopic dynamical polarisation potential was applied to simulate the significant coupling effect to the break-up channel, which is responsible for the observed reduction in the strength of the implemented real potentials. A reasonable agreement between the considered experimental results and the present theoretical calculations was obtained. The study confirms the absence of the usual threshold anomaly present in nuclear systems involving tightly-bound projectiles.
