Precision masses of neutron-rich platinum and gold nuclei reveal enhanced shell strength below doubly-magic Pb
David Freire-Fernández, Rui-Jiu Chen, Usama Ahmed +63
The heaviest stable nuclei in the universe owe their existence to quantum shell structure, the grouping of protons and neutrons into discrete energy levels separated by gaps. The l…
Surrogate neutron-capture studies with fission detection in inverse kinematics at the ESR storage ring
Bogusław Włoch, Camille Berthelot, Guy Leckenby +39
The NECTAR (Nuclear rEaCTions At storage Rings) experiment at the ESR heavy-ion storage ring at GSI/FAIR Darmstadt is dedicated to surrogate reaction studies of neutron-induced rea…
Detector characterization for a new C+C reaction study at LUNA
R. M. Gesùè, S. Turkat, J. Skowroński +50
The C+C fusion reaction plays a crucial role in stellar evolution, including the occurrence of supernova explosions, and in the synthesis of the chemical elements. Ho…
First Proton-Induced Cross Sections on a Stored Rare Ion Beam: Measurement of 118Te(p,γ) for Explosive Nucleosynthesis
F. Dellmann, J. Glorius, Yu. A. Litvinov +75
We present the first nuclear cross-section measurements of (p,γ) and (p,n) reactions on 118Te at energies relevant for the γ-process nucleosynthesis. Absolute cross-section values…
Detectors and Shieldings: Past and Future at LUNA
Chemseddine Ananna, Lucia Barbieri, Axel Boeltzig +11
Nuclear reactions are responsible for the chemical evolution of stars, galaxies and the Universe. Unfortunately, at temperatures of interest for nuclear astrophysics, the cross-sec…
Status and future directions for direct cross-section measurements of the 13C(a,n)16O reaction for astrophysics
L. Csedreki, Gy. Gyürky, D. Rapagnani +45
The 13C(a,n)16O reaction is the main neutron source of the s-process taking place in thermally pulsing AGB stars and it is one of the main candidate sources of neutrons for the i-p…
The Ne(,n)Mg reaction -- state of the art, astrophysics, and perspectives
Andreas Best, Philip Adsley, Ryan Amberger +11
One of the most important stellar neutron sources is the Ne(,n)Mg reaction, which gets activated both during the helium intershell burning in asymptotic giant bran…
Bound-State Beta Decay of Ions and the LOREX Project
R. S. Sidhu, G. Leckenby, R. J. Chen +55
