Probing the exotic structure of

The structure of the exotic 8B nucleus is studied by means of elastic scattering, as well as its breakup on nuclear targets. We present microscopic calculations of the optical potentials (OPs) and cross sections of elastic scattering of 8B on 12C, 58Ni, and 208Pb targets at energies $20 < E < 170$ MeV. The density distributions of 8B obtained within the variational Monte Carlo (VMC) model and the three-cluster model (3CM) are used to construct the potentials. The real part of the hybrid OP is calculated using the folding model with the direct and exchange terms included, while the imaginary part is obtained on the base of the high-energy approximation (HEA) and also taken to be equal to the microscopic real part of the OP. In this model the only free parameters are the depths of the real and imaginary parts of OP obtained by fitting the elastic scattering experimental data. A dependence of their values on the model density of 8 B is found. In addition, the cluster model, in which 8B consists of a p-halo and the 7 Be core, is applied to calculate the breakup cross sections of the 8B nucleus on 9Be, 12C, and 197Au targets, as well as momentum distributions of 7Be fragments, and a comparison with the existing experimental data is made
