Capture of a particles by isospin-symmetric nuclei
(2000-08-14)
The reaction rates for ct capture processes on self-conjugate nuclei in the mass range A = 20-40 have been investigated. The rates were calculated using the statistical model code NON-SMOKER taking into account isospin ...
Low-metallicity inhibition of type Ia supernovae and galactic and cosmic chemical evolution
(1998-08-20)
We introduce a metallicity dependence of the Type Ia supernova (SN Ia) rate into the Galactic and cosmic chemical evolution models. In our SN Ia progenitor scenario, the accreting white dwarf (WD) blows a strong wind to ...
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 ...
The r-process in the high entropy bubble
(1997-08-04)
An approximation for the rp-process
(1997-07-20)
Hot (explosive) hydrogen burning, or the rapid proton capture process (rp-process), occurs in a number of astrophysical environments. Novae and X-ray bursts are the most prominent ones, but accretion disks around black ...
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 ...
