In this paper, the results of the measurements of the total cross sections for the reactions 10,11,12Be+²⁸Si and ¹⁴B+²⁸Si in the beam energy range 13A--47A0.16em0exMeV are presented. The experimental cross sections were obtained by the detection of γ quanta and neutrons accompanying the interaction of the isotopes of Be and B with ²⁸Si. It was found that the cross sections for 11,12Be are similar but significantly exceed those for ¹⁰Be. A significant increase in the cross sections for ¹²Be with decreasing energy is observed in the entire measured energy range. The measured total reaction cross sections are discussed in terms of the reduced strong absorption radius with the empirical Kox parametrization formula and compared with other experimental data and with optical model calculations.
