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

Astrophysical S-factors and reaction rates of (p,n)-reactions on (117)Sn, (118)Sn, (122)Sn, and (124)Sn Skakun, Ye; Rauscher, T. (EDP Sciences, 2008)Astrophysical S-factors and reaction rates were derived from available cross sections of (p,n)-reactions on (117)Sn, (118)Sn, (122)Sn, and (124)Sn isotopes at incident proton energies up to 9 MeV. The statistical theory ...
Skakun, Ye; Rauscher, T. (American Institute of Physics, 2010)Astrophysical S-factors of (p,n) reactions on (99)Ru, (100)Ru, (101)Ru, and (102)Ru were derived from the sum of experimental isomeric and ground states cross sections measured in the incident proton energy range of 5-9 ...
Tables of nuclear cross sections and reaction rates : An addendum to the paper "Astrophysical reaction rates from statistical model calculations" Rauscher, T.; Thielemann, Friedrich-Karl (2001-09)In a previous publication (ATOMIC DATA AND NUCLEAR DATA TABLES 75, 1 (2000)), we gave seven-parameter analytical fits to theoretical reaction rates derived from nuclear cross sections calculated in the statistical model ...
