Elastic scattering angular distributions and heavy residue production cross sections have been measured at different energies around the Coulomb barrier for the systems 6,7Li+64Zn. Optical model fits of the elastic angular distributions were performed using a renormalized double folding potential and absence of usual threshold anomaly in the optical potential was found. Excitation functions for heavy residue production have been measured using an activation technique. Comparison of the data with the results of different calculations show that complete fusion is the dominant reaction mechanism above the barrier, whereas the heavy residue yield below the barrier is mainly due to incomplete fusion and transfer.

In this contribution, results of experiments performed with the three Beryllium isotopes 9,10,11Be on a medium mass 64Zn target, at a center of mass energy of ≈1.4 the Coulomb barrier, will be discussed. Elastic scattering angular distributions have been measured for the 9,10Be reactions. In the 11Be case the quasielastic scattering angular distribution was obtained. In the halo nucleus case, the angular distribution exhibit a non-Fresnel-type pattern with a strong damping of the Coulomb-nuclear interference peak. Moreover, it is found that the total reaction cross-section for the halo nucleus induced collision is more than double the ones extracted in the collisions induced by the non-halo Beryllium isotopes. A large contribution to the total-reaction cross-section in the 11Be case could be attributed to transfer and/or break-up events. [ABSTRACT FROM AUTHOR]

Elastic-scattering angular distributions for the 6Li+64Zn system were measured at energies from below to above the Coulomb barrier. The experimental data were analyzed within the optical model to study the energy dependence of the interaction potential. The results suggest the presence of the breakup threshold anomaly. Preliminary results on the fusion cross-sections for the same system are also reported. [ABSTRACT FROM AUTHOR]

The inverse kinematics thick target scattering method (TTIK) has been used to study the 8Li elastic scattering on 4He in order to investigate 8Li-α cluster configurations in excited states of 12B. A 8Li beam, provided by the radioactive beam facility EXCYT, at Ebeam = 30.6 MeV, passing through helium thick target, continuosly decreases its energy inducing elastic scattering starting from the initial energy down to zero. Four ΔE-E double stage silicon detector telescopes were used to detect the recoil α-particles coming from the scattering. Event by event time measurement between beam particles passing through a MCP detector and α-particles impinging on ΔE stage allows elastic from inelastic events discrimination, thus representing an improvement of the TTIK method. In this paper the used experimental technique and some preliminary results will be briefly described. [ABSTRACT FROM AUTHOR]

Resonant elastic scattering of 13C on a thick 4He target has been measured. Reaction products from 13C(4He,4He) were detected at several beam energies and gas pressures. Raw yield was efficiency corrected using Monte Carlo simulations and an averaged yield spectrum was produced. The observed peaks correspond well to the previously elastic scattering data.

The reactions 9,10,11Be+64Zn have been studied at energies around the Coulomb barrier in order to better understand the role played by the halo features on the reaction dynamics. Preliminary results on such studies will be reported in this paper. [ABSTRACT FROM AUTHOR]
