description: This work is devoted to the process of resonant photodestruction of beryllium-7 nuclei as one of the possible solutions to the lithium problem. We have considered how the addition of monoenergetic photons with an energy equal to the energy of the first excited state of the beryllium-7 nucleus will affect the grid of chemical reactions and, as a consequence, the chemical composition of the Universe during the period of primary nucleosynthesis. The main results of this work were obtained analytically. As it has been shown, the efficiency of nuclear reactions under the same external conditions for different nuclei differs only with different cross-sections of nuclear reactions. An abnormally large cross-section of the deuteron photorestruction reaction leads to the fact that it collapses two orders of magnitude faster in comparison with beryllium-7 and lithium-7 nuclei when photons of a given energy are added to the system. When considering photons with energies equal to the energy of the second excited state of beryllium-7 of the cross-section and, as a consequence, the velocities also differed by two orders of magnitude. With an increase in the photon energy, photodestruction reactions of he-lium-3 become possible, but its photodestruction rate is also higher by an order of magnitude of the photodestruction rate of beryllium-7 and lithium-7 nuclei. This work develops the topic of solving the lithium problem. The main result of this work is that the addition of photons with excitation energies of berylli-um-7 does not lead to more efficient destruction of nuclei of this variety and lithium-7, but only exacerbates the problem of primary lithium. As a consequence, this imposes certain restrictions on the possible ways to explain this problem.
