Energy dependence of optical-model parameters for the interaction of 6Li and 7Li Ions with 28Si nuclei at low energies

Some peculiarities of interactions of weakly bound lithium nuclei at near-barrier energies

“…In this paper we present almost all literature and our data for TCS for [6][7][8][9] Li and 11 Li isotopes obtained in a wide range of incident particles and target nuclei in comparison with Kox systematics (parameterization) and important additional information for light neutron-rich nuclei [13][14][15][16]. Such a comparative analysis of the collection of the experimental (our and literature) data allows us to ensure their reliability, validity and reproducibility for the experiments conducted on different accelerators in different experimental conditions.…”

“…In [11] we presented the experimental ADDCS and TCS data for weakly bound cluster nuclei 6,7 Li and compared the characteristics of their interactions. In this paper, we present new experimental σ R data for 9 Li ions, and the results of joint analysis of all available experimental data for ADDCS of elastic scattering and TCS in a wide range of low energies for 6,7,8,9 Li and 11 Li.…”

In the past decades, the use of the so-called 'multilayer telescope' method enabled scientists to make a considerable progress in the experiments where TCS for beams of exotic nuclei were measured.…”

“…A review of published works shows that there are no reliable experimental measurements of σ R for interactions of exotic nuclei at energies ranging from B c to (10-40) MeV/nucleon. It especially refers to [6][7][8][9] Li and 11 Li nuclei.…”

“…At such high energies, the TCS is more sensitive to the distribution of matter in the crust of the nucleus. In [4] a conclusion about a large length of the neutron density distribution in neutron-rich isotopes 6 He, 11 Li, and 11 Be was first made.…”
