The neutron rich carbon isotope $^{15}$C is the only known case of an almost "pure" 2s$_{1/2}$ single-neutron halo ground state configuration. At collision energies around the Coulomb barrier the reaction dynamics is expected to be dominated by single neutron transfer and breakup [...]

Probing proton halo effects in the $^8$B+$^{64}$Zn collision around the Coulomb barrier
/ Spartà, R (Catania U. ; INFN, Catania) ; Di Pietro, A (INFN, Catania) ; Figuera, P (INFN, Catania) ; Tengblad, O (CSIC, Madrid) ; Moro, A M (Seville U.) ; Martel, I (Huelva U.) ; Fernández-García, J P (Seville U.) ; Lei, Jin (INFN, Pisa) ; Acosta, L (Mexico U. ; INFN, Catania) ; Borge, M J (CSIC, Madrid) et al.
Proton halo effects in the 8B+64Zn reaction at an energy around 1.5 times the Coulomb barrier have been studied at HIE-ISOLDE CERN using, for the first time, the only existing postaccelerated 8B beam. This, together with the use of a high granularity and large solid angle detection system, allowed for a careful mapping of the elastic angular distribution, especially in the Coulomb-nuclear interference region.

In order to investigate the existence of molecular and/or exotic cluster configurations in Boron and Carbon n-rich isotopes we undertook two experiments: the first experimental study of exotic 9Li+α cluster states in 13B using the resonance scattering method at TRIUMF (Canada), and, with the same technique, the measurement of 10Be+α scattering at LNS in Catania, where a 10Be radioactive beam was produced for the first time. In order to measure the excitation function in a wide energy range, the beams were stopped in a Helium-flooded chamber. [...]

This work reports on the scattering of $^{11}$Be on $^{197}$Au at energies around and below the Coulomb barrier. By experimentally identifying the elastic scattering, inelastic scattering and breakup channels, and comparing them with different calculations, valuable information on the $^{11}$Be structure and its $B(E1$) distribution to the continuum are obtained.

The excitation function of the resonant reaction 4He(9Li,α) was measured with the aim of investigating the compound nucleus 13B. These measurements were performed in inverse kinematics at center-of-mass scattering angles close to 180◦ by using a thick 4He gas target and a 9Li beam. [...]

Angular distributions of the elastic, inelastic, and breakup cross sections of the halo nucleus Be11 on $^{197}Au$ were measured at energies below $(E_{lab}=31.9 MeV)$ and around (39.6 MeV) the Coulomb barrier. These three channels were unambiguously separated for the first time for reactions of $^{11}Be$ on a high-Z target at low energies. [...]
