Nuclear astrophysics with radioactive ions at FAIR
R. Reifarth, S. Altstadt, K. Göbel +317
The nucleosynthesis of elements beyond iron is dominated by neutron captures in the s and r processes. However, 32 stable, proton-rich isotopes cannot be formed during those proces…
Suppression of the centrifugal barrier effects in the off-energy-shell neutron+O interaction
M. Gulino, C. Spitaleri, X. D. Tang +27
The reaction O()C was studied at energies from to keV using the quasi-free deuteron break-up in the three body reaction O$+d \righ…
Impact of Nuclear Reaction Uncertainties on AGB Nucleosynthesis Models
S. Bisterzo, R. Gallino, F. Kaeppeler +2
Asymptotic giant branch (AGB) stars with low initial mass (1 - 3 Msun) are responsible for the production of neutron-capture elements through the main s-process (main slow neutron…
Large collection of astrophysical S-factors and its compact representation
A. V. Afanasjev, M. Beard, A. I. Chugunov +2
Numerous nuclear reactions in the crust of accreting neutron stars are strongly affected by dense plasma environment. Simulations of superbursts, deep crustal heating and other nuc…
Time-of-flight mass measurements for nuclear processes in neutron star crusts
A. Estrade, M. Matos, H. Schatz +23
The location of electron capture heat sources in the crust of accreting neutron stars depends on the masses of extremely neutron-rich nuclei. We present first results from a new im…
Astrophysical S-factors for fusion reactions involving C, O, Ne and Mg isotopes
M. Beard, A. V. Afanasjev, L. C. Chamon +3
Using the Sao Paulo potential and the barrier penetration formalism we have calculated the astrophysical factor S(E) for 946 fusion reactions involving stable and neutron-rich isot…
