Neutron capture cross section of Th-232 measured at the n_TOF facility at CERN in the unresolved resonance region up to 1 MeV
(2006-05)
We have measured the neutron capture reaction yield of Th-232 at the neutron time-of-flight facility n_TOF at CERN in the energy range from 1 eV to 1 MeV. The average capture cross section has been extracted in the energy ...
R-matrix analysis of Cl neutron cross sections up to 1.2 MeV
(2006-04)
We have analyzed and evaluated Cl-35, Cl-37, and Cl-nat neutron cross section data in the resolved resonance region with the multilevel Reich-Moore R-matrix formalism. Energies and widths were determined for 388 resonances ...
(n,gamma) cross-sections of light p nuclei
(2006-03)
The nucleosynthesis of elements beyond iron is dominated by the s and r processes. However, a small amount of stable isotopes on the proton-rich side cannot be made by neutron capture and is thought to be produced by ...
Study of the N=28 shell closure in the Ar isotopic chain : a SPIRAL experiment for nuclear astrophysics
(2006-03)
The structure of the neutron-rich nucleus (47)Ar has been investigated through the d((46)Ar,(47)Ar)p transfer reaction. The radioactive beam of (46)Ar at 10 A . MeV was provided by the SPIRAL facility at GANIL. The protons ...
Measurement of the Sm-151(n, gamma) cross section from 0.6 eV to 1 MeV via the neutron time-of-flight technique at the CERN n_TOF facility
(2006-03)
The Sm-151(n,gamma) cross section was measured with the time-of-flight technique from 0.6 eV up to 1 MeV relative to the Au standard with an overall uncertainty of typically 6%. Neutrons were produced by spallation at the ...
Measurement of La-139(n, gamma) cross section
(American Institute of Physics (AIP), 2006)
We measured the neutron capture cross section of La-139 relative to Au-197 in the energy range of 0.6 cV to 9 keV at n_TOF, the neutron time-of-flight facility at CERN. After a description of the experimental apparatus, ...
An updated library of reaction rates for the astrophysical rp-process.
(American Institute of Physics (AIP), 2006)
We are developing an updated library with reaction rates important for the study of the astrophysical rp- process. It includes both experimental and theoretical rates parametrized in terms of the standard REACLIB format. ...
Neutron captures and the r-process
(American Institute of Physics (AIP), 2006)
In order to study possible neutron-capture effects during an r-process, it is necessary to perform fully dynamical simulations. We have performed such calculations within the model of an adiabatically expanding high-entropy ...
Radiative capture reactions and alpha-elastic scattering on Cd-106 for the astrophysical p-process
(American Institute of Physics (AIP), 2006)
In the present work both the (alpha,gamma) and (p,gamma) cross sections on the p-nucleus Cd-106 have been measured in the energy range relevant to the astrophysical p-process. The results are compared with the predictions ...
