Here the interaction between the clusters of the incident nucleus and the target nucleus is described by the phenomenological core functions, 6Li-A amplitude is constructed in the framework of multiple scattering theory oon these clusters. In the work, this approach allowed to analyze the scattering cross sections of a-particles, deuteron and 6Li, containing refraction effects. The formulae for the two-photon form factors of mesons as a function of both photon virtualities were obtained With the help of the resonance chiral theory. The approaches taking into account one and two octets of vector resonances were considered. The differential cross sections of the reaction, averaged over the helicity of the initial state, were calculated. We used a specially designed program - Monte Carlo generator for comparison with the experiment The results are used by collaborations KLOE-2 and BES-III in the analysis of experimental data.
