The astrophysical r-process : A comparison of calculations following adiabatic expansion with classical calculations based on neutron densities and temperatures
(1999-05-01)
The rapid neutron-capture process (r-process) encounters unstable nuclei far from beta-stability. Therefore its observable features, like the abundances, witness (still uncertain) nuclear structure as well as the conditions ...
Explosive nucleosynthesis close to the drip lines
(1998-11)
We give an overview of explosive burning and the role which neutron and/or proton separation energies play. We focus then on the rapid neutron capture process (r-process) which encounters unstable nuclei with neutron ...
First beta-decay studies of the neutron-rich isotopes Sc53-55 and V56-59
(1998-03-16)
The neutron-rich isotopes Sc53-55 and V56-59 have been produced at GANIL in interactions of a 64.5 MeV/u Cu-65 beam with a Be-9 target. They were separated by the doubly achromatic spectrometer LISE3. Beta-decay half-lives ...
rp-process nucleosynthesis at extreme temperature and density conditions
(1998-02)
We present nuclear reaction network calculations to investigate the influence of nuclear structure on the rp-process between Ge and Sn in various scenarios. Due to the lack of experimental data for neutron-deficient nuclei ...
Astrophysical and nuclear physics aspects of the r-process
(World Scientific Publishing, 1998)
The formation of elements as heavy as Th and U and beyond is due to the rapid neutron-capture process (r-process), which causes the production of highly unstable nuclei near the neutron drip-line and functions via neutron ...
Explosive nucleosynthesis and the astrophysical r-process
(American Institute of Physics (AIP), 1998)
We give an overview of chemical equilibria in explosive burning and the role which neutron and/or proton separation energies play. We focus then on the rapid neutron-capture process (r-process) which encounters unstable ...
The r-process in the high entropy bubble
(1997-08-04)
The endpoint of the rp-process
(1997-08-04)
Neutron-rich isotopes Ti-54-57
(1996-12)
The neutron-rich isotopes Ti-54-57 and Cr-58-60 are produced by fragmentation of a 64.5 MeV/nucleon Cu-65(26+) beam in a 90 mg/cm(2) Be-9 target. Following particle identification by energy loss and time of flight, the ...
Astrophysics and nuclei far from stabilitys
(1994-03)
We discuss unstable nuclei on the proton-rich and neutron rich side of stability and their properties of astrophysical relevance. The Coulomb barriers in charged-particle captures lead to a cycle pattern which is not ...
