“…Two years later, Hansen and Jonson [32] proposed the high probability of finding the weakly bound neutrons far away from the 11 Li inner core ( 9 Li), which makes the 11 Li matter density longer and defines it as a nuclear halo. In the same work [32], the existence of a soft dipole resonance was suggested, at low excitation energies, which has been supported by other experimental and theoretical works [33][34][35][36].…”

Investigation of Coulomb dipole polarization effects on reactions involving exotic nuclei

We have analyzed elastic scattering angular distributions and total reaction cross sections of the exotic nuclei 9,11 Li on 208 Pb, at energies below and above the Coulomb barrier. For this purpose, we have used an optical potential with no adjustable parameters, composed by the nuclear São Paulo potential, derived from the nonlocal nature of the interaction, and the Coulomb dipole polarization potential, derived from the semiclassical theory of Coulomb excitation. Within this formalism, we identified an unusual long-range absorption for the 11 Li + 208 Pb system, which is dominated by the Coulomb interaction. We compare it to the absorption mechanisms observed for 6 He + 208 Pb which, unlike those of 11 Li + 208 Pb, take place at small interacting distances, where both Coulomb and nuclear interactions are important. The proposed approach shows to be a fundamental basis to study reactions involving exotic nuclei.

“…The idea of existence of two-neutron halo in 11 Li was experimentally verified in measurements and studies of differential cross sections of the 11 Li+p elastic scattering in the energy range 60-75 MeV/nucleon [21][22][23]. The data analysis at 62 MeV/nucleon [21] showed that the adjusted phenomenological Woods-Saxon (WS) potential has a shallow real part and an imaginary part with a long tail.…”

“…In Refs. [22,23] the data at 65-75 MeV/nucleon were analyzed using the parameter free cluster-orbital shell-model approximation (COSMA) [24] and a conclusion was drawn that the 11 Li+p scattering is mainly determined by scattering on the 9 Li core. In various works (e.g., Refs.…”

Microscopic analysis of11Li elastic scattering on protons and breakup processes within the9Li+2ncluster model

et al. 2013

In the paper, the results of analysis of elastic scattering and breakup processes in interactions of the 11 Li nucleus with protons are presented. The hybrid model of the microscopic optical potential (OP) is applied. This OP includes the single-folding real part, while its imaginary part 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. The depths of the real and imaginary parts of OP are fitted to the elastic scattering data at 62, 68.4, and 75 MeV/nucleon, being simultaneously adjusted to reproduce the true energy dependence of the corresponding volume integrals. The role of the spin-orbit potential is studied and predictions for the total reaction cross sections are made. Also, the cluster model, in which 11 Li consists of 2n-halo and the 9 Li core having its own LSSM form of density, is adopted. The respective microscopic proton-cluster OP's are calculated and folded with the density probability of the relative motion of both clusters to get the whole 11 Li+p optical potential. The breakup cross sections of 11 Li at 62 MeV/nucleon and momentum distributions of the cluster fragments are calculated. An analysis of the single-particle density of 11 Li within the same cluster model accounting for the possible geometric forms of the halo-cluster density distribution is performed.

“…Recently the excitation modes of 11 Li were studied from inelastic collisions with protons making use of the Multiple Scattering expansion of the total Transition amplitude (MST) [7]. In this work good agreement with the experimental data [8] was obtained with a structure model in which there is a pronounced 1 − peak at low continuum energies but yet in which there is not a fully-fledged resonance in this breakup channel.…”
