“…As is known, the problem of the ambiguity of the parameters N arises when the fitting procedure is applied to a limited number of experimental data (see, e.g., the calculations and discussion in our previous works [8][9][10]). Due to the fact that the fitting procedure belongs to the class of the ill-posed problems, it becomes necessary to impose some physical constraints on the choice of the set of parameters N. The total cross section of scattering and reaction is one of them, however, the corresponding experimental values are missing at the energy interval considered in the present work.…”

“…In this work (see also [6,7]), as well as in our previous works considering processes with exotic He isotopes [8][9][10], we use microscopically calculated OPs within the hybrid model [11,12]. In the latter the ReOP is calculated by a folding of a nuclear density and the effective nucleonnucleon (NN) potentials [13] and includes both direct and exchange parts.…”

“…For the 11 Li+p elastic scattering we have used the realistic microscopic LSSM [16,17] density of 11 Li, while the density distributions of 10,11 Be nuclei obtained within the quantum Monte Carlo model [18] and the generator coordinate method [19] are used to calculate the microscopic OPs and cross sections of elastic scattering of these nuclei on protons and 12 C. The main aim of our work is twofold. First, we calculate the differential cross sections of elastic 11 Li and 10,11 Be scattering on protons and nuclei at energies less than 100 MeV/nucleon studying the possibility to describe the existing experimental data by calculating microscopically not only the ReOP, but also the ImOP (instead of using phenomenological one) within the HEA and using a minimal number of fitting parameters. Second, we estimate other characteristics of the reaction mechanism such as the total reaction and breakup cross sections and momentum distributions of the cluster fragments.…”

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.

The fragmentation of neutron-rich 132 Sn nuclei produced in the fission of 238 U projectiles at 950 MeV/u has been investigated at the FRagment Separator (FRS) at GSI. This work represents the first investigation of fragmentation of medium-mass radioactive projectiles with a large neutron excess. The measured production cross sections of the residual nuclei are relevant for the possible use of a two-stage reaction scheme (fission+fragmentation) for the production of extremely neutron-rich medium-mass nuclei in future rare-ion-beam facilities. Moreover, the new data will provide a better understanding of the "memory" effect in fragmentation reactions.

A microscopic analysis of the optical potentials (OPs) and cross sections of elastic scattering of 8B on 12C, 58Ni, and 208Pb targets at energies 20 < E < 170 MeV and 12,14Be on 12C at 56 MeV/nucleon is carried out. The real part of the OP is calculated by a folding procedure and the imaginary part is obtained on the base of the high-energy approximation (HEA). The density distributions of 8B evaluated within the variational Monte Carlo (VMC) model and the three-cluster model (3CM) are used to construct the potentials. The 14Be densities obtained in the framework of the the generator coordinate method (GCM) are used to calculate the optical potentials, while for the same purpose both the VMC model and GCM densities of 12Be are used. In the hybrid model developed and explored in our previous works, the only free parameters are the depths of the real and imaginary parts of OP obtained by fitting the experimental data. The use of HEA to estimate the imaginary OP at energies just above the Coulomb barrier is discussed. In addition, cluster model, in which 8B consists of a p-halo and the 7Be core, is applied to calculate the breakup cross sections of 8B nucleus on 9Be, 12C, and 197Au targets, as well as momentum distributions of 7Be fragments. A good agreement of the theoretical results with the available experimental data is obtained. It is concluded that the reaction studies performed in this work may provide supplemental information on the internal spatial structure of the proton- and neutron-halo nuclei.
