  The astrophysical S-factor for the process p7Be --> 8Bgamma of radiative
capture by the 8B ground state is described up to 5 MeV, within the modified
potential cluster model. The signatures of the S-factor resonances at 0.632,
2.18 and 3.36 MeV due to M1 and E2 transitions from the scattering of resonance
3P1, 3F3 and 3D2 waves to the ground 3P2 state are illuminated using total
cross sections, astrophysical S-factors and reaction rates at temperatures from
0.01 to 10.0 T9. Experimental data on the S-factor are reproduced well in the
range 100 keV to 3 MeV. The importance of the input of the 0.632 MeV resonance
to the reaction rate is proved. Our calculations (performed in advance) confirm
the latest data for the S-factor at 19 keV.
