Title: Study of the possibility of solving cosmological lithium problem in an accelerator experiment

Abstract

Within the standar dmodel of Big Bang Nucleosynthesis (BBN), there is a cosmological lithium problem, which consists in a substantial difference between calculated data on the abundances of the isotopes {sup 6}Li and {sup 7}Li and those that were found from observational astronomy. An attempt at measuring the cross section for the main 6Li production reaction {sup 2}H({sup 4}He, γ){sup 6}Li induced by the interaction of {sup 4}He{sup +} ions with deuterons at collision energies less than the lower boundary of the BBN energy range was made in the present study. Upper limits on the cross sections for the reaction in question were set.
