摘要：Advanced astrophysical reaction-network calculations for the nucleosynthesis of heavy elements within the s, r, and p processes involve ten thousands of reactions. Most of the reaction rates are adopted from calculations based on the Hauser-Feshbach theory. Experimental investigations of photoneutron reaction rates are well suited to test the reliability of these calculations and to constrain the nuclear-physics input relevant for statistical model codes. In this context, recent experimental results stemming from photoactivation experiments are discussed.
