标题： Tests of Transfer Reaction Determinations of Astrophysical S-Factors

摘要： ${}^{16}O ({}^{3}He,d) {}^{17}F$反应已被用于确定到${}^{17}F$基态和第一激发态的渐近归一化系数。 这些系数为${}^{17}F \to{}^{16}O + p$的重叠函数尾部提供了归一化，并使我们能够计算${}^{16}O (p,\gamma){}^{17}F$在天体物理能量下的 S 因子。 计算得到的 S 因子与实验测量结果进行了比较，结果非常吻合。 这首次验证了这种间接方法用于通过转移反应确定天体物理直接捕获率。 此外，我们的结果给出了捕获到$^{17}F$基态和第一激发态的 S(0)，而无需考虑从较高能量外推带来的不确定性。 显示英文摘要

摘要： The ${}^{16}O ({}^{3}He,d) {}^{17}F$ reaction has been used to determine asymptotic normalization coefficients for transitions to the ground and first excited states of ${}^{17}F$. The coefficients provide the normalization for the tails of the overlap functions for ${}^{17}F \to{}^{16}O + p$ and allow us to calculate the S-factors for ${}^{16}O (p,\gamma){}^{17}F$ at astrophysical energies. The calculated S-factors are compared to measurements and found to be in very good agreement. This provides the first 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 $^{17}F$, without the uncertainty associated with extrapolation from higher energies.
