A microscopic analysis of the optical potentials (OPs) and cross sections of elastic scattering of  8 B on  12 C,  58 Ni, and  208 Pb targets at energies 20 &lt; E &lt; 170 MeV and  12,14 Be on  12 C at 56 MeV/nucleon is carried out. The real part of the OP is calculated by a folding procedure and the imaginary part is obtained on the base of the high-energy approximation (HEA). The density distributions of  8 B evaluated within the variational Monte Carlo (VMC) model and the three-cluster model (3CM) are used to construct the potentials. The  14 Be densities obtained in the framework of the the generator coordinate method (GCM) are used to calculate the optical potentials, while for the same purpose both the VMC model and GCM densities of  12 Be are used. In the hybrid model developed and explored in our previous works, the only free parameters are the depths of the real and imaginary parts of OP obtained by fitting the experimental data. The use of HEA to estimate the imaginary OP at energies just above the Coulomb barrier is discussed. In addition, cluster model, in which  8 B consists of a p-halo and the  7 Be core, is applied to calculate the breakup cross sections of  8 B nucleus on  9 Be,  12 C, and  197 Au targets, as well as momentum distributions of  7 Be fragments. A good agreement of the theoretical results with the available experimental data is obtained. It is concluded that the reaction studies performed in this work may provide supplemental information on the internal spatial structure of the proton- and neutron-halo nuclei.
