The path to improved reaction rates for astrophysics
This review focuses on nuclear reactions in astrophysics and, more specifically, on reactions with light ions (nucleons and alpha particles) proceeding via the strong interaction. It is intended to present the basic definitions essential for studies in nuclear astrophysics, to point out the differences between nuclear reactions taking place in stars and in a terrestrial laboratory, and to illustrate some of the challenges to be faced in theoretical and experimental studies of those reactions. The discussion revolves around the relevant quantities for astrophysics, which are the astrophysical reaction rates. The sensitivity of the reaction rates to the uncertainties in the prediction of various nuclear properties is explored and some guidelines for experimentalists are also provided

Determination of the (n,gamma) reaction rate of unstable W-185 in the astrophysical s-process via its inverse reaction Sonnabend, K.; Mengoni, A.; Mohr, P.; Rauscher, T.; Vogt, K.; Zilges, A. (2003-05-05)The (gamma,n) reaction rate of W-186 was measured in order to deduce the (n,gamma) reaction rate of 185 W, an important branching point in the astrophysical s-process. The theoretical predictions have been confirmed and ...
Determination of (n,gamma) reaction rates at s-process branching points via their inverse reactions Sonnabend, K.; Mengoni, A.; Mohr, P.; Rauscher, T.; Vogt, K.; Zilges, A. (2003-05-19)We present our method to determine the (n,gamma) reaction rates of s-process branching point nuclei using data of the inverse (gamma,n) reaction. As an example, we selected Zr-95. The analysis of the data of the reaction ...
Skakun, Ye.; Rauscher, T. (American Institute of Physics, 2008)Astrophysical S-factors for (p,n) reactions on stable Pd isotopes derived from experimental cross sections were compared to statistical model predictions with the NON-SMOKER code. Satisfactory agreement was found. Reaction ...
