Core-collapse supernova explosions triggered by a quark-hadron phase transition during the early post-bounce phase
(2011-06)
We explore explosions of massive stars, which are triggered via the quark-hadron phase transition during the early post-bounce phase of core-collapse supernovae. We construct a quark equation of state, based on the bag ...
The path to improved reaction rates for astrophysics
(2011-05)
This review focuses on nuclear reactions in astrophysics and, more specifically, on reactions with light ions (nucleons and alpha particles) proceeding via the strong interaction. It is intended to present the basic ...
The electron-ion scattering experiment ELISe at the International Facility for Antiproton and Ion Research (FAIR)-A conceptual design study
(2011-05-01)
The electron-ion scattering experiment ELISe is part of the installations envisaged at the new experimental storage ring at the International Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany. It offers ...
Neutron-induced fission cross section of Pb-nat and Bi-209 from threshold to 1 GeV : An improved parametrization
(2011-04-28)
Neutron-induced fission cross sections for Pb-nat and Bi-209 were measured with a white-spectrum neutron source at the CERN Neutron Time-of-Flight (n_TOF) facility. The experiment, using neutrons from threshold up to 1 ...
What are the astrophysical sites for the r-process and the production of heavy elements?
(2011-04)
This article addresses three of the four nucleosynthesis processes involved in producing heavy nuclei beyond Fe (with a main focus on the r-process). Opposite to the fourth process (the s-process), which operates in stellar ...
Mass Measurements of Very Neutron-Deficient Mo and Tc Isotopes and Their Impact on rp Process Nucleosynthesis
(2011-03-21)
The masses of ten proton-rich nuclides, including the N = Z + 1 nuclides (85)Mo and (87)Tc, were measured with the Penning trap mass spectrometer SHIPTRAP. Compared to the Atomic Mass Evaluation 2003 a systematic shift of ...
Au-197(n,gamma) cross section in the unresolved resonance region
(2011-03-17)
The cross section of the reaction Au-197(n,gamma) was measured with the time-of-flight technique at the n_TOF (neutron time-of-flight) facility in the unresolved resonance region between 5 and 400 keV using a pair of C6D6 ...
Determining reaction cross sections via characteristic X-ray detection : alpha-induced reactions on Tm-169 for the astrophysical gamma-process
(2011-01-17)
The cross sections of the Tm-169(alpha, gamma)Lu-173 and Tm-169(alpha,n)Lu-172 reactions have been measured first time using a new method, by detecting the characteristic X-ray radiation following the electron capture-decay ...
How important is the Family? : Alpha nuclear potentials and p-process nucleosynthesis
(SISSA, 2011-01)
In this work we present the results from the analysis of the experimentally measured angular distributions of the reaction 106Cd(α , α )106 Cd at several different energies around the Coulomb barrier. The difficulties that ...
Reaction rate sensitivity of 44Ti production in massive stars and implications of a thick target yield measurement for 40Ca(alpha,gamma)44Ti
(SISSA, 2011-01)
The dynamic synergy between observation, theory, and experiment developed over many years around the field of gamma-ray astronomy has as its ultimate goal observations of specific radionuclides informing our understanding ...
