The nucleosynthesis of heavy elements in Stars : The key isotope 25Mg
(2014-04-14)
We have measured the radiative neutron-capture cross section and the total neutron-induced cross section of one of the most important isotopes for the s process, the 25Mg. The measurements have been carried out at the ...
238U(n, γ) reaction cross section measurement with C 6D6 detectors at the n-TOF CERN facility
(2014-04-14)
The radiative capture cross section of 238U is very important for the developing of new reactor technologies and the safety of existing ones. Here the preliminary results of the 238U(n,γ) cross section measurement performed ...
Measurement of the angular distribution of fission fragments using a PPAC assembly at CERN n-TOF
(2014-04-11)
A fission reaction chamber based on Parallel Plate Avalanche Counters (PPACs) was built for measuring angular distributions of fragments emitted in neutron-induced fission of actinides at the neutron beam available at the ...
Challenges in nucleosynthesis of trans-iron elements
(2014-04-01)
Nucleosynthesis beyond Fe poses additional challenges not encountered when studying astrophysical processes involving light nuclei. Astrophysical sites and conditions are not well known for some of the processes involved. ...
Thermonuclear Ti-42(p, gamma)V-43 rate in type-I x-ray bursts
(2014-03-05)
The thermonuclear rate of the Ti-42(p, gamma)V-43 reaction has been reevaluated based on a recent precise proton separation energy measurement of S-p(V-43) = 83 +/- 43 keV. The astrophysical impact of our new rates has ...
Ni-62(n,gamma) and Ni-63(n,gamma) cross sections measured at the n_TOF facility at CERN
(2014-02-28)
The cross section of the Ni-62(n,gamma) reaction was measured with the time-of-flight technique at the neutron time-of-flight facility n_TOF at CERN. Capture kernels of 42 resonances were analyzed up to 200 keV neutron ...
Experimental neutron capture data of 58 Ni from the CERN n-TOF facility
(2014-01-09)
The 58Ni(n,γ) cross section has been measured at the neutron time of flight facility n-TOF at CERN, in the energy range from 27 meV up to 400 keV. In total, 51 resonances have been analyzed up to 122 keV. Maxwellian averaged ...
