Experimental astrophysicalS-factors for the direct radiative capture processes d(p,γ)3He and 16O(p,γ)17F are analyzed using the modified two-body potential approach. The values of the asymptotic normalization coefficients (nuclear vertex constants) are found for the wave functions of the 3He and 17F nuclei in the (d + p) and (16O + p) channels respectively and are then used to extrapolate the astrophysical S-factor to the region of very low energies.
