Radiative capture reaction(p7,γ)8B at low energies

We calculated the differential cross sections as well as the total cross sections for the /sup 7/Be(p,..gamma..)/sup 8/B at low energies in the radiative direct capture model including the E1, M1, and E2 transitions. The astrophysical S factor at the solar temperature of 20 keV is found to be 0.024 keVX which agrees well with a recent measurement by Filippone et al. We show that the d-wave capture plays an important role in determining the magnitude and shape of S(E) at low energies of astrophysical interest.
