Abstract
Preliminary results of measurements of the total reaction cross sections σ R for nuclei 4 He, 6 He, 8 He, 7 Li, 8 Li, 9 Li, 11 Li, 7 Be, 9 Be, 10 Be, 11 Be, 12 Be, 8 B, 10 B, 11 B and 12 B nuclei at energy range (10-50) AMeV with 28 Si target is presented. The secondary beams of light nuclei were produced by bombardment of the 15N (50 AMeV) primary beam on Be target and separated by COMBAS fragment- separator. In dispersive focal plane a horizontal slit defined the momentum acceptance as 1% and a wedge degrader of 600 µm Al was installed. The B ρ of the second section of the fragment-separator was adjusted for measurements in energy range (10-45) AMeV. The strong absorption model reproduces the A-dependence of σ R , but not the detailed structure. We are comparing our experimental data with predictions of microscopic (dashed line) and strong absorption model, Glauber multiple scattering theory and preliminary results are obtained.

Nowadays one of the major goals of nuclear science is to learn about the behavior of isotopes with exotic neutron to proton number ratios.The production of radioactive ion beams of light nuclides from the 1980s onwards has contributed towards a substantial increase of information on the properties of nuclei far away from the beta stability line, mainly on new aspects of their nuclear structure such as skins, haloes shells and others, in such a way that heavy-ion reaction cross-section measurements can be considered today as an essential tool to investigate the nuclear structure of exotic nuclei
