Preliminary results of measurements of the total reaction cross sections σ R and neutron removal cross section σ -xn for weakly bound 6 He, 8 Li, 9 Be and 10 Be nuclei at energy range (20-35) A MeV with 28 Si target is presented. The secondary beams of light nuclei were produced by bombardment of the 22 Ne (35 A MeV) 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 200 μm Al was installed. The Bρ of the second section of the fragment-separator was adjusted for measurements in energy range (20-35) A MeV. Two-neutron removal cross sections for 6 He and 10 Be and one –neutron removal cross sections 8 Li and 9 Be were measured.
