On the basis of developing potential theory of cluster disintegration of light nuclei the detailed study of two-cluster processes A(g, a)b within the energy range from threshold up E_g~100 MeV to on ⁶Li, ⁷Li, and ⁹Be nuclei is implemented. Using of corresponding potential model cluster wave functions anp, at, and 2an, as well as correct account of final state interactions are the basic standpoints of the given theory. In case of ⁶Li and ⁹Be nuclei the projection of three-cluster wave functions onto different two-cluster channels has been performed. The radiative capture reactions ad ® ⁶Li g and ⁷Li d ® ⁹Be g are also treated within the developed theory. The analysis of observables for the whole set of two-cluster fragmentation reactions was done practically on the microscopic level, i. e., the peculiarities of total cross sections, differential energy and angular distributions, asymmetry and polarization are correlated to energy and angular behavior of multipole and partial transition amplitudes, node structure of cluster wave functions, resonances in scattering channels and others. It was demonstrated that the given theory may not only explain practically all available experimental observables but gives also successful predictionsr.
