The 106Cd(alpha,gamma)110Sn reaction cross section has been measured in the energy range of the Gamow window for the astrophysical p-process scenario. The cross sections for 106Cd(alpha,n)109Sn and for 106Cd(alpha,p)109In below the (alpha,n) threshol

Background: The reaction rates used in gamma-process nucleosynthesis network calculations are mostly derived from theoretical, statistical model cross sections. Experimental data is scarce for charged particle reactions at astrophysical, low energies

It is crucial to measure reaction cross sections relevant to the astrophysical gamma process so that theoretical reaction rates can be tested and validated with experimental data. The total cross sections for the Er-162(p,gamma)Tm-163 and the Er-162(

Background: alpha-nucleus potentials play an essential role for the calculation of alpha-induced reaction cross sections at low energies in the statistical model. Uncertainties of these calculations are related to ambiguities in the adjustment of the

Background: Astrophysical reaction rates, which are mostly derived from theoretical cross sections, are necessary input to nuclear reaction network simulations for studying the origin of p nuclei. Past experiments have found a considerable difference

Production of proton-rich nuclei beyond iron in stars proceeds via the p process, i.e., a sequence of photodisintegration reactions, (gamma,n), (gamma,p), and (gamma,alpha) on heavy nuclei at temperatures of 2-3 x 10(9) K. The involved reaction rates

The statistical Hauser-Feshbach (HF) model performs poorly in calculating the (gamma, alpha) rates that are critical to the p process. Experimental work on elastic scattering of the tellurium isotopic chain [A. Palumbo et al. (unpublished)] provided

The elastic scattering cross sections for the reactions Cd-110,Cd-116(alpha,alpha)Cd-110,Cd-116 at energies above and below the Coulomb barrier are presented to provide a sensitive test for the alpha-nucleus optical potential parameter sets. Addition
