Precision Mass Measurements of 129-131Cd and Their Impact on Stellar Nucleosynthesis via the Rapid Neutron Capture Process
D. Atanasov, P. Ascher, K. Blaum +17
Masses adjacent to the classical waiting-point nuclide 130Cd have been measured by using the Penning- trap spectrometer ISOLTRAP at ISOLDE/CERN. We find a significant deviation of…
Detailed homogeneous abundance studies of 14 Galactic s-process enriched post-AGB stars: In search of lead (Pb)
Kenneth De Smedt, Hans Van Winckel, Devika Kamath +4
This paper is part of a larger project in which we systematically study the chemical abundances of Galactic and extragalactic post-asymptotic giant branch (post-AGB) stars. Lead (P…
On microscopic theory of radiative nuclear reaction characteristics
Sergei Kamerdzhiev, Oleg Achakovskiy, Alexander Avdeenkov +1
A survey of some results in the modern microscopic theory of properties of nuclear reactions with gamma-rays is given. First of all, we discuss the impact of phonon coupling (PC) o…
Experimentally constrained ()Y and ()Y reaction rates relevant to the -process nucleosynthesis
A. C. Larsen, M. Guttormsen, R. Schwengner +18
The nuclear level density and the -ray strength function have been extracted for Y, using the Oslo Method on Y()Y coincidence data. The -ray stre…
Impact of weak interactions of free nucleons on the r-process in dynamical ejecta from neutron-star mergers
Stephane Goriely, Andreas Bauswein, Oliver Just +2
We investigate beta-interactions of free nucleons and their impact on the electron fraction (Y_e) and r-process nucleosynthesis in ejecta characteristic of binary neutron star merg…
Nucleosynthesis in dynamical and torus ejecta of compact binary mergers
Oliver Just, Andreas Bauswein, Ricard Ardevol Pulpillo +2
We present a comprehensive study of r-process element nucleosynthesis in the ejecta of compact binary mergers (CBMs) and their relic black-hole (BH)-torus systems. The evolution of…
