Measurement of the Sm-151(n,gamma)Sm-152 cross section at n_TOF
(2005-07-25)
The Sm-151(n,gamma) Sm-152 cross section, which is important for the interpretation of the Sm-151 branching as an s-process thermometer, was measured from 1 eV up to 1 MeV at the innovative n-TOF facility at CERN. Based ...
Neutron capture cross section measurements for nuclear astrophysics at CERN n_TOF
(2005-07-25)
A series of neutron capture cross section measurements of interest to nuclear astrophysics have been recently performed at n-TOF, the neutron spallation source operating at CERN. The low repetition frequency of the proton ...
The (n,gamma) cross sections of the p-process nuclei Se-74 and Sr-84 at kT=25 keV
(2005-07-25)
The formation of the isotopes on the proton-rich side of the valley of stability cannot be ascribed to neutron capture reactions in the r- or s-processes. These nuclei are produced in the p process, which presumably takes ...
Elastic alpha scattering on Sn-112 and Sn-124 at astrophysically relevant energies
(2005-06)
The cross sections for the elastic scattering reactions Sn-112,Sn-124(alpha,alpha)Sn-112,Sn-124 at energies above and below the Coulomb barrier are presented and compared to predictions for global alpha-nucleus potentials. ...
Neutron capture cross sections for the Re/Os clock
(American Institute of Physics (AIP), 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 ...
