“…Halos had been initially studied through breakup reactions at intermediate and high energies, looking at the momentum distribution of the fragments [48,49]. The relatively low-energy post-accelerated beam at Louvain-la-Neuve opened the possibility for the use of transfer reactions.…”

Abstract.The first beam of post-accelerated radioactive ions was realized in 1989 at the Louvainla-Neuve research facility. The method employed two coupled cyclotrons to produce, separate and re-accelerate the species of interest. Several technological challenges were solved in the process, to obtain pure and intense beams for use in nuclear physics research. Similarly, new techniques were developed and refined for the measurement of the nuclear reactions induced by the radioactive beams. The available energy range made the facility particularly suited for nuclear astrophysics studies, and important results were obtained in the determination of stellar reaction rates using beams of 7 Be, 13 N, 18 F, 18,19 Ne. A beam of 6 He ions was extensively used in studies of the nuclear structure (halos, molecular states) and dynamics (the reaction process at energies around the potential barrier).

“…The ability to produce secondary beams of halo nuclei opened the possibility of investigating their structure by the measurement of the momentum distributions of the fragments coming out after a collision with stable nuclei [13][14][15][16][17][18][19]. The simplest approach to the understanding of Borromean nuclei fragmentation reactions was made by means of the sudden approximation [20][21][22], that assumes that one of the three particles in the projectile is instantaneously removed by the target, while the other two particles remain undisturbed.…”

The formalism to describe electron scattering reactions on two-neutron halo nuclei is developed. The halo nucleus is described as a three-body system (core+n+n), and the wave function is obtained by solving the Faddeev equations in coordinate space. We discuss elastic and quasielastic scattering using the impulse approximation to describe the reaction mechanism. We apply the method to investigate the case of electron scattering on 6 He. Spectral functions, response functions, and differential cross sections are calculated for both neutron knockout and α knockout by the electron.PACS numbers: 25.30. Fj, 25.70.Bc, 21.45.+v

“…Our results confirm the observations (e.g., in Refs. [30,31]) that the width almost does not depend on the mass of the target and as a result, it gives information basically about the momentum distributions of two clusters. Here we note that due to the arbitrary units of the measured cross sections of the considered processes it was not necessary to renormalize the depths of our OPs of the fragments-target nuclei interactions.…”

Abstract. The hybrid model of the microscopic optical potential (OP) is applied to calculate the 11 Li+p,10,11 Be+p,and 10,11 Be+ 12 C elastic scattering cross sections at energies E < 100 MeV/nucleon. The OP's contain the folding-model real part (ReOP) with the direct and exchange terms included, while its imaginary part (ImOP) is derived within the high-energy approximation (HEA) theory. For the 11 Li+p elastic scattering, the microscopic large-scale shell model (LSSM) density of 11 Li is used, while the density distributions of 10,11 Be nuclei obtained within the quantum Monte Carlo (QMC) model and the generator coordinate method (GCM) are utilized to calculate the microscopic OPs and cross sections of elastic scattering of these nuclei on protons and 12 C. The depths of the real and imaginary parts of OP are fitted to the elastic scattering data, being simultaneously adjusted to reproduce the true energy dependence of the corresponding volume integrals. Also, the cluster models, in which 11 Li consists of 2n-halo and the 9 Li core having its own LSSM form of density and 11 Be consists of a n-halo and the 10 Be core, are adopted. Within the latter, we give predictions for the longitudinal momentum distributions of 9 Li fragments produced in the breakup of 11 Li at 62 MeV/nucleon on a proton target. It is shown that our results for the diffraction and stripping reaction cross sections in 11 Be scattering on 9 Be, 93 Nb, 181 Ta, and 238 U targets at 63 MeV/nucleon are in a good agreement with the available experimental data.
