It is commonly assumed that reaction measurements for astrophysics should be preferably performed in the direction of a positive Q value to minimize the impact of the stellar enhancement factor, i.e., the difference between the laboratory rate and the actual stellar rate. We show that the stellar effects can be minimized in the charged particle channel, even when the reaction Q value is negative. As a demonstration, the cross section of the astrophysically relevant 85Rb(p,n)85Sr reaction has…

The activation method for cross section measurements in nuclear astrophysics
Abstract.The primary aim of experimental nuclear astrophysics is to determine the rates of nuclear reactions taking place in stars in various astrophysical conditions. These reaction rates are an
General properties of astrophysical reaction rates in explosive nucleosynthesis
Fundamental differences in the prediction of reaction rates with intermediate and heavy target nuclei compared to the ones with light nuclei are discussed, with special emphasis on stellar
The path to improved reaction rates for astrophysics
This review focuses on nuclear reactions in astrophysics and, more specifically, on reac- tions with light ions (nucleons andparticles) proceeding via the strong interaction. It is intended to
Differences between stellar and laboratory reaction cross sections
Nuclear reactions proceed differently in stellar plasmas than in the laboratory due to the thermal effects in the plasma. On one hand, a target nucleus is bombarded by projectiles distributed in
Alpha-induced reaction cross section measurements on $^{151}$Eu for the astrophysical $\gamma$-process
In order to extend the experimental database relevant for the astrophysical -process towards the unexplored heavier mass region, the cross sections of the 151 Eu(�,) 155 Tb and 151 Eu(�,n) 154 Tb
Systematics of the semimicroscopic proton-nucleus optical potential at low energies relevant for nuclear astrophysics
Background: Astrophysical models studying the origin of the neutron-deficient p nuclides require knowledge of the reaction rates of neutron, proton and α-proton photodisintegrations of pre-existing

TLDR
The main part of the review focuses on the nuclear uncertainties involved in the determination of the astrophysical reaction rates required for the extended reaction networks used in nucleosynthesis studies.
α-induced reaction cross section measurements on 197Au
The γ -process is responsible for creating the majority of the isotopes of heavier elements on the proton rich side of the valley of stability. The γ -process simulations fail to reproduce the
Sensitivity of Astrophysical Reaction Rates to Nuclear Uncertainties
Sensitivities of nuclear reaction rates to a variation of nuclear properties are studied. Target nuclei range from proton- to neutron dripline for 10 ≤ Z ≤ 83. Reactions considered are nucleon- and
Systematic Study Of (p,γ) Reactions On Ni Isotopes
A systematic study of the radiative proton capture reaction for all stable nickel isotopes is presented. The results were obtained using 2.0–6.0 MeV protons from the 11-MV tandem Van de Graaff
