摘要：

The O-16(He-3,d)F-17 reaction has been used to determine asymptotic normalization coefficients for transitions to the ground and first excited states of F-17. Th, coefficients provide the normalization for the tails of the overlap functions for F-17-->O-16+p and allow us to calculate the S factors for O-16(p,gamma)F-17 at astrophysical energies. The calculated S factors are compared to measurements and found to be in very good agreement. This provides a test of this indirect method to determine astrophysical direct capture rates using transfer reactions. In addition, our results yield S(0) for capture to the ground and first excited states in F-17, without the uncertainty associated with extrapolation from higher energies. [S0556-2813(99)00702-5].
