Neutron capture cross sections for the Re/Os clock
(American Institute of Physics, 2005)
The radioactive decay of (187)Re -> (187)Os (t(1/2) = 43 Gyr) is suited for dating the onset of heavy-element nucleosynthesis. The radiogenic contribution to the (187)Os abundance is the difference between the natural ...
Neutron capture cross section measurement of Sm-151 at the CERN neutron time of flight facility (n_TOF)
(2004-10-15)
The Sm-151(n,gamma)Sm-152 cross section has been measured at the spallation neutron facility n_TOF at CERN in the energy range from 1 eV to 1 MeV. The new facility combines excellent resolution in neutron time-of-flight, ...
Predicted cross-sections for photon-induced particle emission
(2004-09)
Cross-sections for the photon-induced particle-emission reactions (gamma,n), (gamma,p), and (gamma,alpha) are given for all natural isotopes from Ti to Bi. The target nuclei are assumed to be in their ground states, except ...
Prediction of astrophysical reaction rates as a challenge to nuclear physics
(2003-05-05)
Explosive nuclear burning in astrophysical environments produces unstable nuclei which again can be targets for subsequent reactions. In addition, it involves a large number of stable nuclides which are not fully explored ...
