“…A lot of effort was put into development and optimization of the active collimators [5] and the method of measurement with an active target. Energy dependence of the total reaction cross section for light neutronrich nuclei 6,8 He, 9,11 Li was measured [6,7], results were successfully interpreted theoretically by the time-dependent Schrödinger equation for 11 Li+ 28 Si [8]. The measurement technique includes detection of prompt gamma-rays accompanying the nuclear reactions, which provide a tag for a reaction event.…”

The construction of the portable spectrometer, MULTI, is designed for the measurement of β-γ-neutron coincidences on beams of radioactive exotic nuclei. It will be used in measurements of the β-decay process of neutron-rich nuclei with large Qβ values accessible in radioactive beams facilities. The experimental technique includes the measurement of the ratios between gamma-ray emission and multi-neutron emission, following beta-decay of radioactive nuclei implanted into an active target. The construction of a gamma-ray spectrometer based on high-volume CeBr3+NaI(Tl) phoswich scintillation detectors is introduced. Results of the measurements of its fundamental characteristics – total detection efficiency, peak efficiency and Compton suppression effect with a 60Co source are presented. Design of the neutron counter array, consisting of 40 proportional counters filled with 3He gas, was optimized with Monte Carlo simulations. Results were validated with a 252Cf spectroscopic source, leading to expected detection efficiency of ∼35% for neutrons with energy < 1MeV. Further development plans are discussed.

“…The latest experimental data on elastic scattering of light weakly bound lithium nuclei 8,9,11 Li indicates enhancement of the total cross section for reactions with these nuclei as compared to reactions with 6,7 Li [1][2][3][4][5][6]. This effect is especially strongly manifested for light nuclei with a neutron halo [7].…”

Neutron transfer and nuclear breakup processes in reaction with weakly bound nucleus 11 Li at energies near the Coulomb barrier are investigated in the framework of the time-dependent Schrödinger equation. The evolution of probability density of outer weakly bound neutrons of 11 Li in the collision with 208 Pb was studied. The probabilities and cross sections of outer neutrons removal (breakup processes and transfer to target nucleus) were calculated. Theoretical predictions of the two-neutron removal probability values were obtained for angles from 140 • to 180 •. The theoretical results have close similarity with experimental data for the two-neutron removal in reaction 208 Pb(11 Li, 9 Li) .
