In this paper, the results of measurements of the total cross sections for the reactions 10,11,12Be+28Si and 14B+28Si in the beam energy range 13A--47A MeV are presented. The experimental cross sections were obtained by detection of the gamma 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. A theoretical explanation of the obtained experimental data is given based on the microscopic model of deformed nuclei and the numerical solution of the time-dependent Schrödinger equation for the outer weakly bound neutrons of the projectile nuclei. The calculated total reaction cross sections are in good agreement with the experimental data.
