Reaction rate of the 7Li(p,γ)8Be radiative capture at low energies

Within the framework of the modified potential cluster model with the classification of orbital states according to Young diagrams, the possibility of description experimental data for S-factor of the proton radiative capture on 7Li to the ground state of 8Be is considered. It was shown that taking into account E1 and M1 transitions from the state of p7Li scattering to the ground state of 8Be in the p7Li channel it is possible to explain the value of the S-factor at energies up to 10 MeV. Based on the calculated total cross sections, the reaction rate in the temperature range of 0.01 to 10.0 T9 is obtained. It is demonstrated that the inclusion of low-lying resonance states gives some contribution into the reaction rate at high temperatures.
