“…Further, in the calculations we use the LSSM density for the 9 Li cluster with rms radius R c =2.31 fm [43] and for the h-halo we probe two densities: the one being described by the Gaussian function (G density) (e.g., [61])…”

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.

“…There are only two or three fitting parameters in the hybrid model that are related to the depths of the ReOP, ImOP and the spin-orbit part of the OP. Along with some phenomenological density distributions for He and Li isotopes we have used in our works realistic microscopic density obtained within the large-scale shell model (LSSM) [48,49]. In the present work devoted to processes with 10,11 Be nuclei we use the density distribution for 10 Be obtained within the QMC model [50,51] and also the densities of 10 Be and 11 Be obtained within the GCM [52].…”

The density distributions of 10 Be and 11 Be nuclei obtained within the quantum Monte Carlo (QMC) model and the generator coordinate method (GCM) are used to calculate the microscopic optical potentials (OPs) and cross sections of elastic scattering of these nuclei on protons and 12 C at energies E < 100 MeV/nucleon. The real part of the OP is calculated using the folding model with the exchange terms included, while the imaginary part of the OP that reproduces the phase of scattering is obtained in the high-energy approximation (HEA). In this hybrid model of OP the free parameters are the depths of the real and imaginary parts obtained by fitting the experimental data. The well known energy dependence of the volume integrals is used as a physical constraint to resolve the ambiguities of the parameter values. The role of the spin-orbit potential and the surface contribution to the OP is studied for an adequate description of available experimental elastic scattering cross section data. Also, the cluster model, in which 11 Be consists of a n-halo and the 10 Be core, is adopted. Within the latter, the breakup cross sections of 11 Be nucleus on 9 Be, 93 Nb, 181 Ta, and 238 U targets and momentum distributions of 10 Be fragments are calculated and compared with the existing experimental data.

“…In particular, for scattering from light nuclei, they used a Helm model to obtain longitudinal form factors. Therein densities obtained from no-core shell model calculations [5,6] also were used. With the He isotopes, they found that the charge density of 6 He differed from that of 4 He but that of 8 He was not significantly different to that of 6 He.…”

The elastic electron scattering form factors, longitudinal and transverse, from the He and Li isotopes and from 8 B have been studied. Large space shell model functions have been assumed. The precise distribution of the neutron excess has little effect on the form factors of the isotopes though there is a mass dependence in the charge densities. However, the form factors of the proton-rich nucleus, 8 B, are significantly changed by the presence of the proton halo.
