The impact of (n,) reaction rate uncertainties of unstable isotopes on the i-process nucleosynthesis of the elements from Ba to W
Pavel A. Denissenkov, Falk Herwig, Georgios Perdikakis +1
The abundances of n-capture elements in the CEMP-r/s stars agree with predictions of intermediate n-density nucleosynthesis, at -$10^{15} \mathrm{cm}^{-3}…
A technique for the study of (p,n) reactions with unstable isotopes at energies relevant to astrophysics
P. Gastis, G. Perdikakis, G. P. A. Berg +20
We have developed and tested an experimental technique for the measurement of low-energy (p,n) reactions in inverse kinematics relevant to nuclear astrophysics. The proposed setup…
Constraining the destruction rate of K in stellar nucleosynthesis through the study of the Ar(p,n)K reaction
P. Gastis, G. Perdikakis, J. Dissanayake +13
40K plays a significant role in the radiogenic heating of earth-like exoplanets, which can affect the development of a habitable environment on their surfaces. The initial amount o…
The impact of (n,) reaction rate uncertainties on the predicted abundances of i-process elements with in the metal-poor star HD94028
John E. McKay, Pavel A. Denissenkov, Falk Herwig +2
Several anomalous elemental abundance ratios have been observed in the metal-poor star HD94028. We assume that its high [As/Ge] ratio is a product of a weak intermediate (i) neutro…
Single-particle shell strengths near the doubly magic nucleus Ni and the Ni(p,)Cu reaction rate in explosive astrophysical burning
D. Kahl, P. J. Woods, T. Poxon-Pearson +24
Angle-integrated cross-section measurements of the Ni(d,n) and (d,p) stripping reactions have been performed to determine the single-particle strengths of low-lying excited…
Constraining the Neutron Star Compactness: Extraction of the Al() Reaction Rate for the -Process
C. Wolf, C. Langer, F. Montes +33
The Al()Si reaction is among the most important reactions driving the energy generation in Type-I X-ray bursts. However, the present reaction-rate uncertainty li…
