The study of exotic nuclei is one of the most important topics in modern nuclear physics. It allows general understanding of the structure and nature of light nuclear systems in the vicinity of the driplines. Most of the leading facilities in the world, CERN, GANIL, GSI in Europe, RIKEN in Japan, and NSCL(MSU) in USA, are involved in these investigations. Recently, new experimental data on the properties of light halo nuclei such as extremely large interaction cross sections, huge electromagnetic dissociation cross sections, narrow momentum distribution of fragments from breakup reactions, unusual modes of the β-decay of these nuclei on the borders of the stability, were obtained.

This Thesis is based on a series of articles devoted to theoretical investigations of nuclearbreakup reactions with light halo nuclei at intermediate energies impinging on light target nuclei. Special attention is paid to the question of sensitivity of the calculated breakup cross sections and longitudinal momentum distributions to the model assumptions and input parameters of the models, involved into the calculations. The nuclear breakup reactions 9Be (D,n), 12C (D,n), 9Be(11Be,10Be), 9Be(15C,14C), 12C(8B,7Be) and 12C (6He,4He) at incident energies from 50 to 2200 MeV/nucleon are studied in the eikonal approximation of the Glauber model.
