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 ...
Neutron capture cross section measurements at n_TOF of Np-237, Pu-240 and Am-243 for the transmutation of nuclear waste
(American Institute of Physics (AIP), 2006)
Accurate and reliable neutron capture cross section data for actinides are necessary for the proper design, safety regulation and precise performance assessment of transmutation devices such as Fast Critical Reactors or ...
Implications of Sm-151(n,gamma) cross section at n_TOF
(American Institute of Physics (AIP), 2006)
The accurate knowledge of the Sm-151(n,gamma) cross section has important implications for the nuclear technologies as well as for fundamental studies. Due to its radioactivity, the only experimental data available on ...
Experimental (n,gamma) cross sections of the p-process nuclei Se-74 and Sr-84
(2006-01)
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 are thought to be produced by ...
Measurement of La-139(n,gamma) cross section at n_TOF
(American Institute of Physics (AIP), 2006)
The capture cross section of the 139La has been measured relative to 197Au standard at n_TOF. We provide here a short description of the experimental apparatus and of the data analysis procedures. The extracted resonance ...
Branchings in the gamma process path revisited
(2006-01)
The location of the (gamma,p)/(gamma,n) and (gamma,alpha)/(gamma,n) line at gamma process temperatures is discussed, using updated reaction rates based on global Hauser-Feshbach calculations. The results can be directly ...
Elastic alpha-scattering on proton rich nuclei at astrophysically relevant energies
(American Institute of Physics (AIP), 2006)
In order to improve the reliability of statistical model calculations in the region of heavy proton rich nuclei several elastic alpha scattering experiments have been carried out at low bombarding energies on various ...
