Within the framework of a modified potential cluster model with forbidden states, the behavior of the astrophysical S-factor for the radiative capture of a proton by 6Li to the ground state (GS) and first excited state (FES) of the 7Be nucleus was reconsidered at energies ranging from 30 keV to 5 MeV. It is shown that, using potentials consistent with the energies of the bound states and the values of the asymptotic normalization constants, it is possible to accurately describe the available experimental data for the astrophysical S-factor. A calculated value of 100 eV·b is obtained at zero energy. The reaction rate of the p6Li capture reaction is calculated at temperatures from 0.001 to 10T9 based on theoretical cross sections. The calculated S-factor and reaction rate results are approximated by simple analytical expressions.
