Experimental study of the (91)Zr(n, gamma) reaction up to 26 keV
(2008-10)
The neutron capture cross sections of the Zr isotopes are relevant to studies in nuclear structure, nuclear astrophysics, and nuclear technology. The valence neutron of (91)Zr with respect to the neutron magic nucleus ...
Cross section measurements of alpha-induced reactions on (92,94)Mo and (112)Sn for p-process studies
(2008-08)
The (92)Mo(alpha, n)(95)Ru, (94)Mo(alpha, n)(97)Ru, and (112)Sn(alpha, gamma)(116)Te cross sections were measured at the upper end of the p-process Gamow window between 8.2 and 11.1 MeV. Our results are slightly lower than ...
Measurement of the (90,91,92,93,94,96)Zr(n,gamma) and (139)La(n,gamma) cross sections at n_TOF
(EDP Sciences, 2008-06)
Neutron capture cross sections of Zr and La isotopes have important implications in the field of nuclear astrophysics as well as in the nuclear technology. In particular the Zr isotopes play a key role for the determination ...
Neutron capture cross section of (90)Zr : Bottleneck in the s-process reaction flow
(2008-03)
The neutron capture cross sections of the Zr isotopes have important implications in nuclear astrophysics and for reactor design. The small cross section of the neutron magic nucleus (90)Zr, which accounts for more than ...
176Lu/176Hf : A sensitive test of s-process temperature and neutron density in AGB stars
(2008-01-20)
The s-process branching at A (176) has been analyzed on the basis of significantly improved experimental cross sections. This work reports on activation measurements of the partial (n, gamma) cross section of Lu-176 feeding ...
Neutron resonance spectroscopy at n_TOF at CERN
(EDP Sciences, 2008)
Neutron resonance spectroscopy plays an important role in the investigation of neutron induced reaction cross sections and nuclear structure in the MeV excitation range. Neutron time-of-flight facilities are the most used ...
p-Process simulations with a modified reaction library
(2008-01)
We have performed p-process simulations with the most recent stellar (n, gamma) cross sections from the Karlsruhe Astrophysical Database of Nucleosynthesis in Stars project (version v0.2, http://nuclear-astrophysics.fzk. ...
Simultaneous measurement of the neutron capture and fission yields of (233)U
(EDP Sciences, 2008)
We have measured the neutron capture and fission cross section of 233 U at the neutron time-of-flight facility n_TOF at CERN in the energy range from 1 eV to 1 MeV with high accuracy by using a high performance 4 pi BaF(2) ...
Improved lead and bismuth (n,gamma) cross sections and their astrophysical impact
(EDP Sciences, 2008)
A series of (n,gamma) neutron capture measurements on the lead isotopes and bismuth have been carried Out at the CERN n_TOF installation in the neutron energy range from 1 eV up to 1 MeV. At n_TOF, contaminations due to ...
Recent results at n_TOF and future perspectives
(American Institute of Physics (AIP), 2008)
The neutron Time-of-Flight facility at CERN has been used for a series of neutron capture and fission cross sections measurements. The facility, detectors and data analysis techniques are described, followed by a brief ...
